Bebop Riddle, for expert marimba soloist, is virtuosic, playful, dance-like, nuanced, and nimble. A bit like Stravinsky and Bartok crossed with Bebop, with an occasional hint of a Big-Band-like brass fill, the composition unfolds chains, links, collisions, alterations, and deviations. Like an engine with several kinds of motors, wheels and cogs, the music churns and hops along at a fast tempo, unfurling a chain-link of transformations, variations and outgrowths. Musical connections are orbital; sounds cross-fertilize and establish relationships which, in turn, create new intersections, amalgams, and fulcrum points. The spirit of this work is that no two chords, motives, lines, phrases, rhythms are exactly the same. Everything is transforming - everything is an amalgam.
