The Bowie/Shaw is not so good - rather erratic, Shaw often splashing away a bit, and Bowie not too inspired. As I remembered it, in fact, but I did not want to diss it without giving it a listen, as it's been several years.
If someone is still interested, I have that date on the first release on this site. It has Bowie's two other Muse albums, and they're quite good, as I remember (I did only re-listen to the duo date so far).
