Gloria Coates's personal sound world is unlike any other in contemporary music. Her 'Piano Quintet' is rooted in the poetry of fellow American pioneer Emily Dickinson, with half of the quartet tuned a quarter-tone higher than the other, the strange beauty of the music emerging in glacial landscapes and shimmering microtones. Coates's 'Symphony No. 10' evokes the archaeological ruins of a Celtic tribe, inspiring a torrent of dramatic percussion and long held tones that curve and shake in a moving body of sound. Gloria Coates is the most prolific female symphonist in musical history, and Naxos has an emerging series of her symphonic, chamber and other major works. Of her Symphony No. 15, released on a previous Naxos recording, Fanfare wrote: "the new symphony is still a jaw-dropper." In general, the symphonies on Naxos come attached to other larger-scaled works and the chamber music (predominantly quartets) is programmed together. This is the first release to program a symphony and a chamber work in the same album.
