Composer Pauline Oliveros is a maverick in the field of electronic music. Oliveros' first instrument was the accordion; as a teenager in Texas she played in a 100-piece accordion group that appeared at the rodeo. In 1949 she entered the University of Houston, but in 1952 transferred to San Francisco State College. Oliveros studied music privately with Robert Erickson and began to associate with a loose confederation of like-minded composers; Terry Riley, Steve Reich, and Morton Subotnick among them.
Mauricio Kagel (born in Buenos Aires, December 24, 1931, died in Cologne, September 18, 2008) was an Argentine composer who has lived in Germany for most of his career. He was most famous for his interest in developing the theatrical side of musical performance. Many of his pieces give specific theatrical instructions to the performers, such as to adopt certain facial expressions while playing, to make their stage entrances in a particular way, to physically interact with other performers and so on.
