Like everyone I have a lot of favorites, but I guess my all-time favorite would be Pat Mastelotto. His playing with David Sylvian, King Crimson and especially Stick Men is a constant inspiration for me. Electronics, acoustics, little percussion toys, multiple odd time signatures or simple grooves - to me he covers all the bases. He's also very diverse with his recording projects and I stay on top of all of them. A player who can adapt is a player who has a long career.
Don‘t forget his playing on XTC’s Oranges and Lemons.
