17   Jack White
of the White Stripes

White has become the hottest new thing on six strings by celebrating the oldest tricks in the book: distortion, feedback, plantation blues, the 1960s-Michigan riff terrorism of the Stooges and the MC5. Onstage, decked out like a peppermint dandy, he violates classic covers (Dolly Parton's "Jolene," Bob Dylan's "Isis") with fireball chords and primal, bent-string scream. He is also an acute orchestrator in the studio, stirring the scratchy-78s atmosphere of Blind Willie Johnson sides, 1970s punk and Led Zeppelin-style drama into his own howl. Don't pay attention to the notes; White is not a clean soloist. He's a blowtorch.

Jimmy Page
of Led Zeppelin

In the 1970s, there was no bigger rock group in the world than Led Zeppelin and no greater god on six strings than Zeppelin's founder-captain Jimmy Page. Nothing much has changed. The imperial weight, technical authority and exotic reach of Page's writing and playing on Zeppelin's eight studio albums have lost none of their power: the rusted, slow-death groan of Page's solo, played with a violin bow, in "Dazed and Confused," on Zeppelin's 1969 debut; the circular, cast-iron stammer of his riffing on "Black Dog," on the band's fourth LP; the melodic momentum and chrome-spear tone of his closing solo in Zeppelin's most popular song, "Stairway to Heaven." Page actually built Zeppelin's sound and might from a wide palette of inspirations and previous experience. In the early and mid-1960s, Page was a first-call studio musician in London, playing on Kinks and Everly Brothers dates and honing his production skills on singles for John Mayall and future Velvet Underground vocalist Nico. And before forming Zeppelin in London in the late summer of 1968 with singer Robert Plant, drummer John Bonham and bassist John Paul Jones, Page had been the lead guitarist in the final lineup of the Yardbirds.
