In 1968, the sound that would become known as heavy metal began to coalesce. That January, the San Francisco band Blue Cheer released a cover of Eddie Cochran's classic "Summertime Blues," from their debut album Vincebus Eruptum, that many consider the first true heavy metal recording.[73] The same month, Steppenwolf released its self-titled debut album, including "Born to Be Wild," with its "heavy metal" lyric. In July, another two epochal records came out: The Yardbirds' "Think About It"?B-side of the band's last single?with a performance by guitarist Jimmy Page anticipating the metal sound he would soon make famous; and Iron Butterfly's In-A-Gadda-Da-Vida, with its 17-minute-long title track, a prime candidate for first-ever heavy metal album. In August, The Beatles' single version of "Revolution," with its redlined guitar and drum sound, set new standards for distortion in a top-selling context. The Jeff Beck Group, whose leader had preceded Page as The Yardbirds' guitarist, released its debut record that same month: Truth featured some of the "most molten, barbed, downright funny noises of all time," breaking ground for generations of metal ax-slingers.[74] In October, Page's new band, Led Zeppelin, made its live debut. In November, Love Sculpture, with guitarist Dave Edmunds, put out Blues Helping, featuring a pounding, aggressive version of Khachaturian's "Sabre Dance." The Beatles' so-called White Album, which also came out that month, included "Helter Skelter," then one of the heaviest-sounding songs ever released by a major band.[75] The Pretty Things' rock opera S.F. Sorrow, released in December, featured "proto heavy metal" songs such as "Old Man Going."[76]
