Both groups are pseudonyms for producer Rollo Armstrong, a member of the band Faithless.
She also performed guest vocals on both of Dido's albums, and has written for a variety of artists including Melanie C, Paolo Nutini and One Eskimo.
In 1999, her song "Addicted", originally released as solo B-side track to her single "Come Down", was reworked by Faithless.
The new version retained Taylor's vocal performance while adding a new rap by Maxi Jazz.
Taylor released a self-titled solo album in 1999 on Cheeky Records, which spawned the underground club hit single "Constantly Waiting".
