"Karlheinz Stockhausen (August 22, 1928 – December 5, 2007) was a German composer, widely acknowledged by critics as one of the most important but also controversial composers of the 20th and early 21st centuries. He is known for his ground–breaking work in electronic music, aleatory (controlled chance) in serial composition, and musical spatialization. ...

"Delia Derbyshire was working in the BBC's Radiophonic Workshop in 1963 when she was given the score for a theme tune to a new science fiction series.
She turned those dots on a page into the swirling, shimmering Doctor Who title music – although it is the score's author, Ron Grainer, who is credited as the composer.
Now David Butler, of Manchester University's School of Arts, Histories and Cultures has revealed for the first time the existence of 267 tapes found in Ms Derbyshire's attic when she died in 2001.
They were, until last March, in the safekeeping of Mark Ayres, archivist for the Radiophonic Workshop – and have lain unheard for more than 30 years."

"This year marks the 50th anniversary of the Radiophonic Workshop, the BBC's experimental unit for electronic sound. It also marks the 10th anniversary of the workshop's death after a long period of decline. But almost as soon it was gone, it began to assume cult status. A Radiophonic ghost began to haunt the peripheries of pop culture, audible initially as an influence on 'retrofuturist' groups such as Boards of Canada, Broadcast and Add N to (X). In the past five years, there has been a steady flow of Radiophonic–related reissues from labels such as Mute, Rephlex, Glo–Spot and Trunk; a BBC4 documentary, Alchemists of Sound; and a South Bank symposium organised by Saint Etienne's Bob Stanley. There have been two plays about the workshop's Delia Derbyshire, and when Doctor Who was relaunched in 2005, unfavourable comparisons were made between the Radiophonic team's original electronic music and the orchestrated flatus of Murray Gold's updated version. This summer, the Southbank Centre held a symposium on Daphne Oram, the workshop's co–founder, and there was news about the discovery of a huge cache of unreleased material by Derbyshire, the workshop's most brilliant composer. In November, Mute is set to issue a double CD compilation, 50th Anniversary Retrospective, including nuggets never before released."

Iannis Xenakis is one of the most important composers of the 20th century. His works span every media and numerous approaches, electronic and acoustical, from orchestral to electroacoustic to multi–media. Also a mathematician, experimental engineer and architect, theoretician, educator, and author, Xenakis is a true renaissance figure.
