The core TERMINATRYX configuration of Paul & Sonja are occasionally joined by a range of musicians mainly for live purposes and occasionally recording where necessary.

Past and present, they include (alphabetically):

Ronnie Belcher (drums)
Malcolm Burger (guitar)
Patrick Davidson (guitar)
Brett Reynolds (guitar)
Tom Somers (guitar)
Christina Storm (backing vocals)
Braam Villiers (guitar)

For those still confused, Christina has not been involved with TERMINATRYX since 2003. As additional backing vocalist to lead singer Sonja, she was only part of its initial idea and merely recorded some demo backing vocals before leaving - one segment of which was retained for the opening of the song "Midnight". She is however behind the band in all of its endeavours. This has changed nothing to the TERMINATRYX sound, attitude or commitment, Christina's selected backing vocals now merely replaced by that of lead vocalist Sonja.
