Sin Fronteras by Rick Dior is an ensemble piece that blends jazz harmony, Latin grooves, and contemporary fusion writing. Scored for mallet keyboards, cajón, bongos, and drumset, the work features rhythmically intricate passages, odd time signatures, and opportunities for improvisation for the vibraphonist and percussion section.

Players comfortable with modern Latin styles—especially on drumset—will find ample room for expressive interpretation. Suggested performance approaches include using bundle rods on drumset for balance and playing the hand percussion parts in traditional seated positions. Sin Fronteras offers ensembles a groove-forward, harmonically rich work that showcases multiple soloists while maintaining Dior’s signature blend of precision, energy, and sharp writing.

This piece ships as a fully bound score. Individual parts come exclusively in PDF format.
