Crystal Spheres can be best described as an exuberant piece of music that employs elements of jazz, funk, rock and Latin. Even with those styles at play, one must not assume the work to be light and easy. On the contrary, it has moments of excitement and beauty that are challenging for the players and engaging for the listening audience. This is Mr. Morales's first trumpet ensemble composed in 1992 and newly revised for this publication.
Instrumentation 4 B flat Trumpets, 4 Flugelhorns, Acoustic Bass and Drum Set.
