Schoenberg was one of Glenn Gould's favorite composers, and this selection of songs provides a fascinating rendering of the notorious Viennese modernist. The Book of the Hanging Garden is eerie and expressionist, but other earlier works are Straussian: it's always illuminating to be reminded of Schoenberg's debt to 19th-century Romanticism. And anything marked by Gould's Midas touch, of course, belongs near the CD player. --Joshua Cody
