I didn't realize that I'd been catching music by the brilliant British guitarist and songwriter John Martyn, on the occasional Eric Clapton or Phil Collins album, until it was too late; he passed away in 2009. His greatest album was 1973's atmospheric and bluesy Solid Air, and you can listen to the greatest track off it played live with a wonderful folk trio here. But for tonight, a mellow late-80s jazz-pop number, with David Gilmour of Pink Floyd handling the electric lead. Beautiful.
