2016 edition. Remastered. "One of the greatest modern moments on Blue Note – ever! From the cover, to the compositions, to the playing on the set – the whole album crackles with an unbelievable fire that was hardly ever matched again. A young Sam Rivers leads a quartet that includes Jaki Byard on piano, Ron Carter on bass, and Anthony Williams on drums – coming together in a sound that's got lots of sharp edges, yet which also beats with an undeniably swinging heart. Rivers blows incredibly on the session – held in check by the rhythm section, and never getting too free (or sloppy, as on some later sides) – and instead hitting these hard tones that really push the envelope of 60s jazz without rewriting the rules entirely. Brilliant all the way through" Dustygroove
