Cannonball Adderley’s Somethin’ Else, one of the few albums featuring Davis as a sideman, is a monument to that type of discourse. Like Davis’ Kind of Blue, recorded with Adderley the following year, it is calm and uncluttered and direct, each line and phrase contributing something crucial to the whole. Indeed, Somethin’ Else is a kindred jazz classic, a sibling of sorts to Kind of Blue. Among other sterling attributes, it shares that landmark’s emphasis on stark, easy-to-appreciate melodies.
