Instruments in progressive rock

[black max]

A few extra mentions to spur further discussions:

Andy Mackay plays a beautiful oboe on a number of Roxy Music toons.

Patrick Moraz likes odd Brazilian percussion and features it extensively on his "I" album.

Lots of horns and woodwinds on a variety of Crimson albums, along with a kalimba. Maybe the kalimba was Jamie Muir's contribution; can't remember the track off the bat.

Personally, I love the "stick," and Trey Gunn's variant, the Warr guitar.

I'm leaving out a hell of a lot of stuff, particularly the cello -- one of my favorites.
