I have a lot of the later live archival stuff, and enjoy it, but it's all Randy California. If you enjoy the idea of him doing extended takes on classic titles, it's for you, But the pop sensibilities of Jay Ferguson and the dynamics of John Locke are long gone, If you like Ferguson (I do), check out the four albums by Jo Jo Gunne. Those are probably the next purchase after the four classic Spirit titles, ahead of the later California Spirit titles.
