I've long been a John Martyn fan and have several of his albums. His guitar playing broke new ground.

Much in the same way that his tunings were selected for fullness and warmth, to make up for the lack of other instrumentation, Martyn’s slap-and-pop technique adds rhythm and bite. In a sense, his right thumb was his drummer.'
He's my guitar hero. I first saw him at Sweetwaters festival in 1980. It was just on sunset and we were in the front row. Martyn came onto the stage smoking a joint which he threw into the audience. The crowd responded by throwing joints onto the stage... loads of them. Welcome to New Zealand.
Between every number he'd pick up a joint, light it, take a couple of puffs then throw it into the audience. We caught one of them so I can modestly say I shared a joint with John Martyn.
Also caught him at Mainstreet in Auckland and twice in the UK. He was better without a backing band. Just John and his echo box and his music was sublime.
