Sphere Ensemble is Colorado’s exciting new chamber ensemble, freeing itself from the confines of the baton and presenting the power and richness of the string orchestra paired with the intimacy of a string quartet.Sphere was formed in 2011 by professional string players who wanted to explore new directions in string ensemble playing. The members of Sphere bring a wealth of musical experiences into the group, all having classically-based college or conservatory training but possessing a diverse background of musical loves and tastes. Sphere musicians have appeared with groups and musicians ranging from the Colorado Symphony and Boulder Philharmonic, to Moby and Kanye West, and nearly every style in between. They have perfomed in Denver, Boulder, and Broomfield, and have been featured on Colorado Public Radio’s Colorado Spotlight show with Charley Samson, and KGNU’s Classic Monday.The inspiration for the group came from a self-conducted performance by the string sections of the Academy of St. Martin in the Fields. Sphere’s founder, Beth Rosbach, knew that there was a select group of talented musicians in the Denver metro area that could perform superbly in that exact configuration, and after three years of dreaming was able to gather those musicians together for the group’s debut.Sphere has the goal of becoming a permanent fixture in Colorado’s music scene. We want to perform great music from multiple styles and genres, and engage audiences with the on-stage communication and camaraderie that radiates from a quality self-directed group. We want our distinctive approach and energetic music-making to bring in audience members who wouldn’t normally attend a typical classical music ensemble concert.

Sphere musicians currently perform with: Boulder Philharmonic, Colorado Opera, Greeley Philharmonic, Colorado Symphony, Central City Opera, Colorado Springs Philharmonic, Fort Collins Symphony, Cheyenne Symphony, and Ensemble Pearl. Individual Spherists also regularly appear with the Mont Alto Motion Picture and Tango Orchestra, FEAST, Danielle Ate the Sandwich, Covenoven, Wadirum, Blow the Vault, Extasis, and The Belle Jar.
