Ceiling treatment question

My basement music room is 27' x 13' with an 8.5' ceiling. The ceiling is acoustical ceiling tile in a grid and I want to get rid of this. I'm tired of the "office look". I don't want to drywall the ceiling but I want a finished look like drywall. One idea is to have 2' x 2' interlocking tiles glued or screwed to the ceiling joists. I've investigated beadboard and other panels but the look doesn't do much for me. I've thought outside the box and considered carpeting the ceiling (carpet tacked to the joists? I must be goofy.) and I've also thought about leaving the ceiling exposed and spray painting the joists, ducts, conduits, etc. Owens Corning makes a stretch fabric called Solserene for applications like this but I can't find a store to see the product. I'd like to hear ideas about what to use for the ceiling. Also, I want to deaden the sound of footsteps from marble tile in the kitchen which is partly above the room. Will standard Armstrong thermal/acoustical insulation help absorb the sound from above? I would put the insulation between the joists. Thanks for any ideas.
