While the ensemble's instrumentation has varied over the years, it has generally consisted of amplified woodwinds (typically saxophones, flutes, and bass clarinet), keyboard synthesizers, and solo soprano voice (singing solfeggio).
In 2011, individuals from the ensemble performed a series of concerts in an installation at the Metropolitan Museum of Art in the Temple of Dendur exhibit.
From 2012 until late 2015 the ensemble has presented, along with many other performers, a revival of Einstein on the Beach which opened in Montpellier, France in 2012.
In early September 2014 the ensemble performed with Steve Reich and other musicians at the Brooklyn Academy of Music's "Next Wave Festival."
Glass has also collaborated with them on their most recent album, Final Answer, and many of his works are featured in performance by SFGC (artistically directed by Ensemble vocalist and keyboardist Lisa Bielawa).
