William John Evans was an American jazz pianist and composer who mostly played in trios. His use of impressionist harmony, inventive interpretation of traditional jazz repertoire, block chords, and trademark rhythmically independent, "singing" melodic lines continues to influence jazz pianists today.

What's New is an album by jazz pianist Bill Evans with flautist Jeremy Steig which was released in 1969 on the Verve label. Actually this is a quartet set with guest flutist Jeremy Steig, whose playing recalls Herbie Mann's recording (Nirvana) with Evans back in the early '60s. Both flutists were always open to the influences of pop and rock although in both of their collaborations with Bill Evans, the music is very much on the pianist's turf. With the exception of Evans' "Time Out for Chris" and the "Spartacus Love Theme," the songs performed on this date would fit securely in the Miles Davis repertoire of the late '50s. Steig is in particularly fine form on the program which includes tunes such as "Straight No Chaser," "Autumn Leaves" and "So What."
