Wikipedia : This day (September 15, 1980), in Fort Lee, New Jersey,, died William John Evans a.k.a. Bill Evans, an American jazz pianist.
Bill Evans Memorial Library index : Bill’s contribution as a leader and composer ensures him a place in jazz history. He must be regarded as one of the most innovative pianists of all time. The very personal harmonic language that he perfected through systematic reharmonizations of standards has influenced an entire generation of musicians.
The BILL EVANS Webpages : His last trio was formed in 1978, featuring the incomparably sensitive Marc Johnson on bass and drummer Joe LaBarbera, which rejuvenated the often-ailing pianist, who was elated with his new line-up, calling it the most closely related to his first trio (with LaFaro and Motian).
@last.fm : He worked briefly with Miles Davis and was the pianist on all but one track of Kind of Blue (1959). In fact, although “Blue in Green” is credited to Davis, Evans always claimed that it was his own composition and that some years later Davis gave him $25 as compensation for lost royalties.
