Inside, 5000 Spirits is full of whimsical delights. It was produced by Robin Williamson and Mike Heron once they had returned from travels. Robin himself had managed to pick up a variety of different instruments in Morocco and they all seem to get in there somewhere. Clive Palmer who had started the String Band with Robin had gone off to Afghanistan and did not rejoin the others. 5000 Spirits was quite unlike anything else that was around at the time. Anyone expecting something like Disraeli Gears or Odessey & Oracle would have been surprised by what the String Band was offering. The fusion of folk, blues, psychedelia and, certainly what we now call World Music, gave 5000 Spirits a unique sound that has guaranteed a place in music history.
