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.
Tom Carter is best known for his work with Charalambides, which he co-founded with longtime creative partner (and one time wife) Christina Carter in 1991. Carter has also undertaken solo work and numerous collaborations with Bardo Pond, Vanessa Arn, Robert Horton, Ian Nagoski, Tower Recordings, Double Leopards, Yellow Swans, Starving Weirdos, and Jandek, among others.
