Russell Platt has some good capsule reviews in the New Yorker of his picks for best classical recordings in 2007. Included is Corigliano: Music for String Quartet:
Half magus, half magpie, this quintessential New York composer assembles works of piercing tenderness from the shards of twentieth-century music. The Corigliano Quartet plays its signature piece with persuasive devotion; a startlingly mature quartet by Corigliano's student Jefferson Friedman rounds out the album.
I also just found Pediaphon, a web gadget that reads aloud Wikipedia articles. Here's an audio version of the John Corigliano entry (Windows only). The composer's name is mispronounced and the overall effect is choppy but useful nonetheless.
