Feldman, Palais de Mari and Crumb, A Little Suite for Christmas performed by pianist Steven Osborne (Hyperion). It isn’t just the ability to play Morton Feldman’s music that marks a virtuoso pianist as special it’s the desire to do so. Our luck in Buffalo in hearing Feldman’s slow, soft, visionary music for so long while he was the Varese Professor of Music at UB (his invention) doesn’t usually translate to the endeavors of a pianist like Steven Osborne, whose interest in the likes of Liszt and Alkan as well as Ravel and Beethoven Sonatas doesn’t promise affinity for a composer known to advise pianists to listen to the tone a single finger can make. But not only does Osborne prove to be devoted to Feldman he cleverly pairs him on a disc with George Crumb. The pieces performed here are Feldman’s Intermission 5, Piano Piece 1952 and Exteriors 3 all from 1952, as well as his 25-minute final piece for piano Palais de Mari from 1986. (He died in 1987.) The altogether more eventful Crumb works are the 1980 A Little Suite for Christmas and the 1983 Processional.
