On Monday, October 20, Mr. Warburton is giving a master class and recital at the University of Washington in Seattle. A brief Internet search indicates he's done the same at several other universities in the U.S. I can find no reviews or comments on his playing. I'd be happy to read a few reviews/opinions/reactions from those of you who've attended his recitals. In Seattle, he'll be playing "Fire" by Gareth Wood, "Almost Swing" by himself, "Sonata in 6:30" by Claude Pascal, "Tubaroque" by Roger Boutry, and the world premier of "Trunk" by Adam Gorb. There is no piano accompanist listed. Is all of this repertory for unaccompanied bass trombone?

Thanks for your replies.
