Like the best guitar heroes, Ben Folds, pianist and leader of a guitarless trio called the Ben Folds Five, commands and fuels his small, tightly wound ensemble with an authoritative, nearly virtuosic style. Folds, based in Chapel Hill, North Carolina, borrows from everywhere but lends new inspiration and insight to the instrument's possibilities--he's the Jimi Hendrix of the baby grand. His frenetic keypounding eclipses old-time styles from honky-tonk to Jerry Lee Lewis rag, and he outplinks megastars such as Elton John and Billy Joel while sifting them both through the mondo hammerings of classic pop-loving alternative keyboard bashers like Todd Rundgren and Squeeze's Jools Holland.
