Bradford Alexander "Brad" Mehldau (/ˈmɛlˌdaʊ/; born August 23, 1970) is an American jazz pianist, composer, and arranger.
Mehldau studied music at The New School, and toured and recorded while still a student. He was a member of saxophonist Joshua Redman's Quartet with bassist Christian McBride and drummer Brian Blade in the mid-1990s, and has led his own trio since at least 1992. His first long-term trio featured bassist Larry Grenadier and drummer Jorge Rossy; in 2005 Jeff Ballard replaced Rossy. These bands have released a dozen albums under the pianist's name.
