Anything with the drumming of Michael Giles - I have always loved this guys drumming and I just had a raving mad passion to hear him again - he appeared on all sorts of odd albums in the early 70's after leaving King Crimson -

In particular I've been listening to everything by the 21st Century Schizoid Band made of alumni from King Crimson....any Crimson fan should check them out. Look at the line up
Jakko Jakszyk - guitar, lead vocals, keyboards, flute
Ian McDonald - alto saxophone, backing and lead vocals, flute, keyboards, piano, percussion
Mel Collins - alto, tenor and baritone saxophones, backing vocals, flute, keyboards,
Peter Giles - bass, backing vocals, percussion
Michael Giles - drums, backing and lead vocals, percussion
I've also been listening to the last 3 albums by Jackson Heights as he played on those albums: https://en.wikipedia.org/wiki/Jackson_Heights_(band)
he has a light, crisp, jazz influenced progressive rock style - he's a great but under rated British rock musician imho. (as is his brother - the bass player Pete)
