2LP set that brings together 2 (then) unreleased sessions recorded by Sam Rivers for Blue Note during the mid 60s! The first album was later issued as Dimensions & Extensions – and features Sam Rivers starting to stretch out and get kind of free in a bit of a Blue Note late 60s New Thing mode, but still hanging back from the freer side he'd explore on later recordings for Impulse. James Spaulding, Donald Byrd, Julian Priester, and Cecil McBee are in the larger piano-less band which Rivers would later move away from as he started playing in more trio and small group settings. 6 tracks in all: "Precis", "Paean", "Effusive Melange", "Involution", "Afflatus" and "Helix". Next up is extremely dark material recorded by
Andrew Hill as a leader, but featuring Rivers on tenor – a quartet date that's filled with jagged edges and bold fragments of sound! There's a really strong new thing vibe going on here – at a level that matches the brilliance of
Hill's Smokestack album, but which is perhaps even better, given Rivers' sharp lines on tenor! As with many of the best Blue Note sets in this mode, the bass and drums almost get equal space with the main solo instruments – so that the percussion of JC Moses and bass of Walter Booker often hang out in space, shaping the sound of the record on their own, as all players contribute equally to the structure of the songs.
Hill wrote all the numbers on the set, and titles include "Violence", "Pain", "Illusion", "Hope", "Lust", and "Desire".
