In the 1960s, Handy led several groups, among them a quintet with Michael White, violin, Jerry Hahn, guitar, Don Thompson, bass, and Terry Clarke, drums. This group’s performance at the 1965 Monterey Jazz Festival was recorded and released as an album; Handy received Grammynominations for “Spanish Lady” (jazz performance) and “If Only We Knew” (jazz composition).
