This piece is based on the rhythms of a drumline cadence called "Givin' It Up Again" from the 2002 season of the Boston Crusaders Drum Corps. The original cadence was composed by Rich Viano, Lee Hanson and Mike Nelson.
The compositional process involved arranging the snare, tenor and bass drum parts into guitar, bass, accordion and trumpet. The piece was composed in sections and the drum set parts was performed separately.
Melodies and harmonies were added to the work to connect sections which were simply rhythmic in nature. The listener who is familiar with the original cadence might not recognize the underlying piece but that is the nature of adapting strictly percussive works to melodic and harmonic instruments. I have provided links below to listen to the tune.
The title of the piece is derived from "Xennial" which is the term for a micro-generation of people born between 1977 and 1983.
