It was a Tuesday afternoon in March of 1979, and the global music world was practically vibrating with a new, disruptive frequency. The debut album from Van Halen had been out for exactly thirteen months, and in that remarkably brief span of time, it had sold over two million copies. It wasn’t just the sheer sales volume that had the entire industry talking; it was a specific track, a blistering, instrumental tour de force known simply as “Eruption.” This single piece of recorded music had caused working guitarists around the globe to literally put down their instruments, stare at their stereos in absolute bewilderment, and reconsider their entire fundamental relationship with the electric guitar. Overnight, it established a twenty-three-year-old virtuoso named Eddie Van Halen as the most heavily discussed, heavily scrutinized, and hotly debated guitarist in all of rock music.
The fierce argument buzzing through the halls of recording studios, local dive bars, and the editorial offices of music magazines was not about whether Eddie was impressive. That fact was not seriously in dispute among anyone with functional hearing. The true debate was fundamentally about what that breathtaking impression actually meant. What category did this wild playing belong to? Did the mind-boggling technique he had seemingly brought to the mainstream represent a genuine, foundational advance in the vocabulary of the instrument? Or was it something vastly more limited than that—a spectacular, flashy novelty that would age the way all novelties age: quickly, predictably, and with rapidly diminishing returns?
Many traditional purists firmly believed that when the dust settled, it would leave behind nothing more than the fleeting memory of a moment when something weird had happened before rock music safely returned to its established, comfortable paths. Enter Paul Mercer, a seasoned journalist who had a very definitive, immovable position on this exact question. He was about to discover, in the most profoundly humbling way imaginable, that his ironclad position had a fatal flaw.
Paul Mercer was a respected, authoritative voice in the tight-knit guitar community. He wrote for Guitar World, had been thoroughly covering the chaotic realm of rock music for six years, and had developed a rigid set of strongly held opinions about what constituted serious musicianship and what constituted cheap theatrics. These opinions were not formed from ignorance or casual observation. They were forged from genuine, lifelong engagement with the instrument and its rich history. Mercer had twelve years of practical playing experience under his belt, combined with six years of analyzing professionals who played significantly better than he did. He was certainly not dismissive of Eddie Van Halen’s raw ability. In fact, he had listened to the band’s debut album carefully, spinning the vinyl over and over with the focused, analytical attention of a man trying to dissect a complex puzzle rather than just enthusiastically reacting to it. He recognized that something genuinely unusual was happening.
However, Mercer was deeply skeptical of the specific technique that had brought Eddie to global attention: the revolutionary two-handed tapping. This technique had been continuously analyzed, debated, and, in some stringent circles, outright condemned in the glossy pages of every guitar publication on the newsstands. Mercer’s position, which he had confidently stated in print not once, but twice in the preceding year, was unflinching. Tapping, he argued passionately, was merely a speed technique, absolutely not a musical technique. It allowed a guitarist to play fast flurries of notes that could not otherwise be executed at that velocity, which was, of course, impressive in the way that any athletic physical feat performed at top speed is impressive. But Mercer believed it produced a very specific, limited kind of note—percussive, thin, and entirely lacking the lush, expressive dynamic range of conventionally picked playing. To him, this severely limited its practical musical application to a very narrow range of contexts. It was spectacular in a flashy solo, perhaps, but totally unnecessary everywhere else. It was, in his eyes, essentially a parlor trick. A brilliantly executed trick, yes, but a trick nonetheless.
Mercer arrived at the scheduled interview gripping his notebook, his portable tape recorder, and his intact, unwavering skepticism. He was fully prepared to intellectually spar with whatever weak counterargument Eddie might offer. He absolutely did not expect the counterargument to take the physical, undeniable form that it eventually did.
Eddie Van Halen greeted him at the heavy door of a nondescript rehearsal space in Hollywood, a low-ceilinged room with carpeted walls that the band utilized between their grueling tour schedules. The air was thick, smelling faintly of rubber cable insulation, stale coffee, and the specific, lingering warmth of a room where loud music has been played for hours on end. Eddie, just twenty-three years old, was clad simply in worn jeans and a casual t-shirt. He welcomed Mercer with the easy, disarming openness of someone who approaches media conversations the same way he approaches life: without a shred of particular anxiety and with a genuine, boyish curiosity about where the interaction might lead.
They sat down on opposite sides of a flimsy folding table. Mercer methodically set up his tape recorder, ensuring the spools were ready to capture the debate. Eddie sat with an unplugged electric guitar resting casually across his knees. It wasn’t a prop; it was just there, existing as a natural extension of his body, the way a pen is ever-present for a dedicated novelist.
Mercer began exactly where he had meticulously planned to begin. He asked probing questions about the tapping technique: how it had organically developed, what the underlying musical intention was, and how Eddie mentally categorized it within the broader context of his overall approach to the fretboard. It was a fair, journalistic inquiry, and Eddie answered it fairly. He traced the fascinating development from his early, isolated sonic experiments in his childhood bedroom in Pasadena, California, all the way through the gradual, painstaking refinement over years of playing in dimly lit local clubs where nobody in the audience was watching closely enough to notice—or care—what his hands were actually doing.
Then, Mercer smoothly pivoted to the confrontation he had come to initiate. He looked Eddie in the eye and delivered his prepared thesis. “The criticism,” Mercer stated, framing his words with careful deliberation, “is that tapping produces a note that is fundamentally different from a picked note. It has far less dynamic range, much less tonal variation. The argument is that it is inherently limited as a viable musical tool because it can only really do certain, specific things.”
Eddie listened patiently, completely unfazed. “Well, what do you say to the fact that it entirely depends on what you’re trying to do?” Eddie replied gently.
“But doesn’t that logic apply to literally any technique?” Mercer countered, leaning in. “The real question is whether this particular technique truly expands what is possible on the instrument, or whether it just does one specific, repetitive thing faster than it could otherwise be done by normal means.”
“It expands what’s possible,” Eddie stated plainly. He said it without a hint of defensiveness, offering it as a simple, factual statement of a deeply considered reality.
Mercer saw his opening. “Can you actually demonstrate that?” he asked. “And I don’t mean playing ‘Eruption.’ I’ve heard ‘Eruption’ a hundred times. Show me something that proves the technique is doing something that conventional playing simply cannot do. Something inherently musical, not just blindingly fast.” Mercer delivered this challenge with the profound, unshakable confidence of a man who had thought through his argument from every conceivable angle and believed it to be perfectly sound. The request was genuine; he wasn’t trying to maliciously trap the young rock star. He had simply concluded, through intense analysis and personal reflection, that the musicality he was asking to see did not actually exist.
Eddie looked at the journalist in silence for a long, heavy moment. “You play guitar?” Eddie asked quietly.
“I’ve played for twelve years,” Mercer replied, a touch of pride in his voice.
Without another word, Eddie physically held out his beloved guitar across the folding table. Mercer stared at it, completely taken aback. This was absolutely not on his meticulously prepared interview itinerary.
“You want me to play?” Mercer asked, confused.
“I want to show you something,” Eddie said softly. “It’s much easier if you feel it for yourself than if I just sit here and try to explain it to you.”
Cautiously, Mercer reached out and took the instrument. He was a highly competent player—twelve years of serious, disciplined study, a solid working knowledge of complex music theory, and a technique that was “correct” in all the rigid ways that a decade of formal lessons produce correctness.
