This is probably the finest joint effort from John and Beverley Martyn, before he launched into a meteoric solo career that eventually crashed into drug addiction. Most of it is forgettable folk-rock -- but the title track (the final one on the album) is John Martyn as we know and love him, with gravelly, meditative vocals and pyrotechnical guitar work. I don't say the whole album is worth buying for this one track, but it IS pretty impressive!
