The Crusaders' debt to Art Blakey's Jazz Messengers wasn't hard to miss -- except that the L.A.-based unit had no trumpeter, and became known for its unique tenor/trombone front line. Sample, a hard-swinging player who could handle chordal and modal/scalar improvisation equally well, stuck to the acoustic piano during the Crusaders' early years -- but would place greater emphasis on electric keyboards when the band turned to jazz-funk in the early '70s and dropped "Jazz" from its name. Though he'd recorded as a trio pianist on 1969's obscure Fancy Dance, 1978's Rainbow Seeker was often described as his first album as a leader. In contrast to the gritty music the Crusaders became known for, Sample's own albums on MCA and, later, Warner Bros. and PRA generally favored a very lyrical and introspective jazz-pop approach. Sample died of mesothelioma in September 2014 in Houston, Texas at the age of 75. In 2015, Sample's holiday-themed collaboration with vocalist India.Arie, Christmas with Friends, was posthumously released. ~ Alex Henderson
