"This is music that by its very nature is well left of the mainstream field, yet the players of the San Francisco-based Del Sol Quartet – an ensemble that specialises in contemporary and neglected cutting-edge scores – sound completely inside its rarefied sound world. Unlike, say, the LaSalle Quartet, which tended to impart a cool, intellectual unflappability (wonderful for the Schoenberg quartets), the Del Sol players produce a gloriously opulent, full-throated tone that prevents exuberantly inventive writing from catching an expressive chill. Warmly recorded and perceptively played, this is music well worth getting to know." --Julian Haylock, The Strad (July 2009)

"The music holds the listener's interest in large part thanks to the excellent performance of the Del Sol Quartet, a San Francisco–based group that champions contemporary composers and brings to these works total technical control and musical commitment." – Edith Eisler, Strings (August 2009)

"Prepare yourself for the sleek, muscular control and organic integrity of music that one of America's coolest composers wrote in hid mid 20s, between 1927 and 1932 ... Sarah Cahill and the quartet identify so closely with the music that they are able to create emotional tension with just the slightest changes in volume and tone, as if the interpretative route lies in not thinking in terms of goal but of process. Working at Skywalker Sound, the production team headed by Charles Amirkhanian has found a raw physical strength in the sound that perfectly fits the music's spirit." Laurence Vittes, Gramophone (September 2009)
