If the opening guitar lick, springy groove and shifting keys of “You Know What I Mean” don't make it clear, the sprightly bass confirms it—this is the record where Jeff Beck goes full funk, using his virtuosic guitar chops to send listeners running to the dance floor. "Thelonius" even finds Beck using a talk box to sing lyrics written by Stevie Wonder, with the soul legend himself joining in on clavinet to add his inimitable swing to this jazz-funk classic.
