Sub Rosa presents another installment in its Early Electronic series, a silver vinyl reissue of Trevor Wishart's Red Bird: A Political Prisoner's Dream, composed between 1973 and 1977 using the studio of the University of York, and originally released in 1978 by York Electronic Studios. Wishart's compositional interests deal mainly with the interpolation by technological means between the human voice and natural sounds. He has been very active since the early 1970s in the area of electro-acoustic music (first with tape manipulation, later with computer pieces) and music theater pieces. He pays special attention to musical education, collaborative performance projects, and solo practice using original vocal techniques. In 1973 he did his doctoral dissertation at the University of York in musical composition. Since the mid '70s he has been doing systematic research into vocal sounds and speech articulation and the possibilities for their notation and musical organization, giving special emphasis to computer technologies. He is the author of a number of theoretical books on musical composition, philosophy, and sociology and has contributed to the design and implementation of software tools used in the creation of digital music.
