Elizabeth Parker (also credited as Liz Parker) provided special sounds for the Doctor Who television story The Stones of Blood and the incidental music for the Doctor Who story Timelash. She was the only woman ever credited with providing special sounds for Doctor Who.
Her incidental music suite for Timelash was released on 30 Years at the Radiophonic Workshop.
As a member of the BBC Radiophonic Workshop, Parker also served as the composer and music advisor for Blue Veils and Golden Sands, a story which sought to honour Delia Derbyshire. She also provided the special sounds for most of the run of Blake's 7, along with scoring one episode of that show.
