(with Cream) and Page (with Led Zeppelin) became famous after leaving the Yardbirds.

But Beck remained a relatively obscure figure. This despite the fact that the hits following "I'm a Man"—"For Your Love," "Shapes of Things," "Over Under Sideways Down," "Happenings Ten Years Time Ago" —were all powered by his brilliantly manic lead guitar. In comparison, Clapton was an extremely conservative stylist and Page, merely a technician. But Beck's guitar work was visionary: "Shapes of Things" shows his mastery over raga-style guitar solos and multitracking, ideas which were in their infancy at the time. Beck experimented with blues progressions, using feedback and other distortion techniques to push the electric guitar's expressive capabilities into new areas, as well as developing rock and R&B styles along the same lines.

After leaving the Yardbirds, Beck made a classic solo album, Truth, with a band which included Rod Stewart and Ron Wood. Page, meanwhile, formed his own band, Led Zeppelin, whose music was a variation on Beck's concept (compare the versions of "You Shook Me" on Truth and the first Zeppelin album). He returned two years later with a jazz-accented R&B outfit based around keyboardist Max Middleton and singer Bob Tench.

Their two albums featured a lighter, more progressive guitar style. But Beck was still not satisfied and tried a brief, disastrous fling into heavy metal with the ex-Vanilla Fudge/Cactus rhythm section of bassist Tim Bogert and drummer Carmine Appice.

Last year, producer George Martin reunited Beck and Middleton for their greatest collaboration, Blow by Blow, which became Beck's best-selling solo album and established him firmly in the jazz-rock hierarchy. But Beck was only developing ideas he'd been playing with for years.

On Wired, Beck invites a direct and favorable comparison with John McLaughlin (with whom he toured last year) by collaborating with ex-Mahavishnu keyboardist Jan Hammer and his band. Martin didn't score any of the horn arrangements because Hammer's synthesizer fills all those spaces, but the album is better recorded and has a much fuller sound than Blow by Blow. Middleton's contribution is still essential—his one song, "Led Boots," opens the album at its hottest pace and it's definitely enhanced by the interplay with Hammer's keyboards and Beck's guitar.
