Composer and pianist Mehldau stumbled on the music of John Coltrane and Charlie Parker when he was 12 years old. He's been a jazz freak ever since. He made his name as a sideman for legends like Michael Brecker, Joshua Redman, and Wayne Shorter. Last year, Mehldau released Quartet, a collaboration with guitarist Pat Metheny. At this week's concert, Mehldau hooks up with drummer Jeff Ballard and bassist Larry Grenadier, both of whom played on Quartet. Expect plenty of new takes on jazz standards as well as much free improvisation on some of Mehldau's own songs. Plus, the trio has been covering Radiohead's "Exit Music (for a Film)" onstage, which gives the guys plenty of space to showcase their chops.
