OK, a bit of explanation:
Prince’s albums Sign O the Times was a collection of songs recorded with a couple different groups (as well as some by himself), as a result of a few different projects being combined. A similar thing happened with Elvis Costello’s Spike album, where he recorded in four different studios around the world, with different personnel in each studio, and he ended up in his words combining about 4 different albums of ideas into the one.
This is what I am looking for. Although I don’t want to rule anything out, I am more interested in different groups of people playing along to each track (rather than one band playing multiple different styles, for example), and hopefully different groups of instruments being involved.
Anyone have any ideas?
