Miles Davis - 'Round About Midnight (LP)

Miles Davis' first album for Columbia, 'Round About Midnight, represents both the beginning of a three-plus-decade relationship with the famed label as well as the start of an extended collaboration with then-unknown saxophonist John Coltrane. As one of the era's only complete start-to-finish full-length LPs, the 1957 set stands as a hard-bop benchmark – a summation of the styles that came before its creation, an immersion into the period's cutting-edge strains, and a hint of the rivoluse modalism that would follow.
