John Baker and Delia Derbyshire.
First compiled in 1968 as an in-house BBC Library LP, this was given a full commercial release in 1970 and was the first sampling of the Radiophonic Workshop's output. This CD is a great snapshot of the RW's output from their three principle composers of the period. John Baker's compositions are by and large the most 'hummable' but Delia Derbyshire's 'Pot au Feu' is remarkable - almost her CV in musical form.
