J. G. Thirlwell IS Foetus. So I'm going to take off the "of Foetus".
Thirlwell acts as the sole instrumentalist, vocalist, songwriter and producer for all Foetus works and as such is the only member of the band. Other artists may occasionally collaborate with Thirlwell on Foetus works but are not considered members of Foetus. Thirlwell is solely responsible for the musical output of the band.
