Other recent orchestral works include The Styx (2024), commissioned by the ENSEMS Festival and premiered by the Orquestra de València under Baldur Brönnimann. Critic Justo Romero described the work as revealing Colomina i Bosch’s “precise yet fluid writing” and “unique and unmistakable style”, calling it “a new masterwork of Spanish music.” His solo violin piece Shpigl (2016), commissioned by the Yehudi Menuhin International Violin Competition, was described by composer John Adams as “a small masterpiece of both musical and dramatic imagination,” and was later programmed by Adams in the Los Angeles Philharmonic’s Green Umbrella series at the Walt Disney Concert Hall.

Colomina i Bosch’s music has been commissioned and performed by institutions and ensembles including the Orquesta y Coro Nacionales de España, Philharmonia Orchestra, Aldeburgh Festival, Orquestra de València, Orquesta Sinfónica del Principado de Asturias, Real Filharmonía de Galicia, Oviedo Filarmonía, Orquesta Sinfónica de Tenerife, Trío Arbós, Grup Instrumental de València and the Schubert Ensemble.
