Ted Templeman heard Eddie Van Halen warming up at Sunset Sound - and insisted they record it immediately.
For three years, Eddie had been playing an unaccompanied solo during Van Halen's shows at Hollywood clubs like the Whisky a Go Go. It was his spotlight moment - a chance to show what he'd been working on alone in his bedroom, the techniques he'd been developing since he was sixteen.
The solo featured something guitarists simply didn't do in 1977: two-handed tapping. Eddie would use both hands on the fretboard, hammering out notes at impossible speeds, creating cascades of sound that didn't seem physically possible on six strings. He'd seen Jimmy Page do something similar during "Heartbreaker" - raising his right hand high while tapping rapid-fire notes with just his left - and Eddie had filed the technique away, thinking about its potential.
But Eddie and the band knew the technique was special. David Lee Roth explicitly told him: "When you tap, turn your back to the crowd so that they can't see what you're doing." As often as not, Eddie would perform the solo with his back to the audience in those Hollywood clubs, shielding the technique so no one could steal it.
Michael Anthony remembered watching Eddie develop the tapping early on: "We just tripped because none of the other guitar players in the local bands were doing anything like that." The band told him, "Man, keep that canned up. We don't want that to get out. That's your thing."
But to Eddie, the solo itself was just a warm-up - something he ran through before shows to get his fingers ready. It wasn't special enough to put on a record.
By late September 1977, Van Halen was deep into recording sessions for their debut album at Sunset Sound Recorders in Los Angeles. They'd been tracking since late August, working with producer Ted Templeman to capture the raw energy of their club performances. Eddie had brought his homemade Frankenstrat and his Marshall turned up to 10, trying to get the songs to sound exactly like they did live.
One day, toward the business end of the sessions, Eddie was rehearsing for an upcoming show at the Whisky. Templeman stepped out of the control booth to grab a coffee.
That's when he heard it.
Eddie was extemporizing variations on a classical theme - running through his solo, working out the kinks, making sure his fingers remembered the patterns. The sound coming from the studio was unlike anything Templeman had heard before. Rapid-fire hammer-ons and pull-offs. Blur-speed runs. Two-handed tapping. Whammy bar dive-bombs.
Templeman walked back into the control room, blown away.
"What is that?" he asked.
Eddie looked up. "Nothing. Just something I warm up on."
Templeman didn't hesitate. "We gotta record it. Right away."
Engineer Donn Landee looked at Templeman and smiled. "Already rolling."
Eddie did it about two or three times before they got a version he liked. The take they kept was one minute and forty-two seconds. Eddie made a mistake at the top end - something that would bother him for the rest of his life - but they kept it anyway and moved on.
The piece that Eddie had been hiding from audiences for three years - the solo he'd play with his back turned so no one could steal his technique - was now on tape. Templeman slotted it as the second track on the album.
When Van Halen's debut was released on February 10, 1978, that warm-up exercise became "Eruption."
Guitar Player magazine's editor played it for the Keyboard magazine editor and asked, "Is that a keyboard or a guitar?" Journey's Neal Schon got an advance copy three months before touring with Van Halen and admitted, "I could not figure it out. It drove me nuts." Within months, it was virtually impossible to walk into a music store without hearing some kid trying to replicate it.
Eddie never intended it to be on the record. He thought it was just a warm-up - something he did before shows, nothing special.
Ted Templeman heard otherwise.
