"Eruption" starts with a short accompanied intro with Alex Van Halen on drums and Michael Anthony on bass. The highlight of the solo is the use of two-handed tapping. "Eruption" was played on the Frankenstrat, with an MXR Phase 90, an Echoplex, a Univox echo unit and a 1968 Marshall 1959 Super Lead tube amp. The Sunset Sound studio reverb room was also used to add reverb. The Frankenstrat was tuned down a half-step. "Eruption" begins in the key of A flat and ends on an E flat note that is a twelfth fret, 6th string harmonic processed through a Univox EC-80 echo unit.
Inspiration
The "Eruption" introduction is based on the "Let Me Swim" introduction by Cactus.[6] After the intro, an E-flat major quotation of the "Etude No. 2" by Rodolphe Kreutzer is heard. The end section begins with a series of rapid two-handed tapping triads that have a classical like structure and eventually finishes with a repeated classical cadence followed by sound effects generated by a Univox EC-80 echo unit.[2]
The piece that would later be named "Eruption" had existed as part of Van Halen's stage act at least as far back as 1975, when it featured no tapping.[7][better source needed] Although one-handed tapping (hammer-ons and pull-offs) was standard guitar technique, "Eruption" introduced two-handed tapping to the mainstream popular rock audience, and it was a popular soloing option throughout the 1980s.
Initially, "Eruption" was not considered as a track for the Van Halen album as it was just a guitar solo Eddie performed live in the clubs. But Ted Templeman overheard it in the studio as Eddie was rehearsing it for a club date at the Whisky a Go Go and decided to include it on the album. Eddie recalled, "I didn't even play it right. There's a mistake at the top end of it. To this day, whenever I hear it, I always think, 'Man, I could've played it better.'"[8]
"Spanish Fly", an acoustic guitar solo on Van Halen II, can be viewed as a nylon-string version of "Eruption", expanding on similar techniques. Similarly, it was suggested by Templeman for inclusion on the album after he heard Eddie Van Halen playing a classical guitar. In March 2005, Q magazine placed "Eruption" at number 29 in its list of the 100 Greatest Guitar Tracks. "Eruption" has been named the 2nd greatest guitar solo by Guitar World magazine.[9] Chuck Klosterman of Vulture.com named it the best Van Halen song, noting "if you love Van Halen, this is what you love, and you can listen to it a thousand times without diminishing returns."[10]
