Plus Minus: Repeat Music

Aldo Clementi's Madrigales; Morton Feldman's Bass Clarinet and Percussion; Bernhard Lang's 'DW6a'; Alvin Lucier's 'I am sitting in a Room'; and Philip Glass's 'Music in Contrary Motion'. (This programme explores different approaches to repetition in music. Although none of the music is literally repetitive, these diverse works share common interests, in creating music out of an extreme economy of means and opening up different kinds of listening environments.)
