Here is a 32 year old John Coltrane sharing a studio recording session with trumpeter Wilbur Harden and a bunch of young lions such as Tommy Flanagan (piano) Doug Watkins (bass) and Louis Hayes (drums), plus Curtis Fuller (trombone) Ali Jackson (bass) Howard Williams (piano) and Art Taylor (drums) on couple of tracks. in 1958 Coltrane was deeply exploring the Hard Bop idiom, that's when the saxophonist was still playing around with Monk and Davis and just before he would begin leading his own groups. A fine document!
