The group was unofficially dissolved in 2001 when Fischer invited Erol Unala to contribute to the reformation of Celtic Frost.

Subsequently managed by Rod Smallwood and Merck Mercuriadis, Apollyon Sun released a five-track debut mini-album - God Leaves (And Dies) on London's Mayan Records in summer of 1998 and then contributed "God Leaves" and "Relinquished Body" for the soundtrack of top-rated BBC TV show City Central.

Work on a full album, Sub, began at London's Trident Studios that same year, with producer Roli Mosimann (Björk, Marilyn Manson, Faith No More).

In 2001 and 2002, Apollyon Sun made further soundtrack contributions for the BBC, among them music for the high profile TV production Red Cap with Tamzin Outwaithe.

Unala and Fischer also participated in former Nirvana drummer Dave Grohl's (Foo Fighters) Probot album project.
