 All Leslie recordings were later licensed to Joseph Weinburger, and Leslie's recordings were pressed onto a short series of 78rpm library discs, occasionally being put to use in science and mystery based programing, such as early "Doctor Who" episodes.He used a great number of tape sources to create his pieces; some sources he mentions in his liner notes are motor horns, humming tops and bells.In 2005, Jonny Trunk's British record label, Trunk Records, re-released Desmond's 1960 acetate, never before released commercially.
