Alongside Bob Dylan, Fred Neil and a local folk singer called Bob Gibson, Callier was discovering John Coltrane, who had just released his free jazz album A Love Supreme. "He was playing at a little club called McKees, and I got there early to see Elvin Jones nailing his drum kit to the floor. Then the quartet rocks on stage, and I wasn't prepared for the intensity with which these guys threw themselves into the music - I had never seen men do that before in my life and it frightened me. It made me realise that everything in life was in this music: the beautiful and the ugly, the godly and ungodly. Not everybody wants to touch those places because there are things we have to forget in order to live with ourselves, and that music didn't let you have any secrets.
