As opposed to Thirlwell's other instrumental group, Steroid Maximus, Manorexia features no collaborators and eschews musical structure for a more free-form and spontaneous approach. The results are often described as cinematic and textural. To date all albums have been released on Thirlwell's own Ectopic Ents label and have been sold only at concerts or via the Official Foetus Website.
"The Mesopelagic Waters" album has been released in March 2010 on John Zorn’s Tzadik Records label. It contains tracks from the first two Manorexia albums and is performed by a chamber ensemble.
"Dinoflagellate Blooms" is a studio album of all-new material and is released in both stereo and 5:1 surround.
The band was chosen to perform at the ATP I'll Be Your Mirror festival curated by ATP & Portishead on September 2011 in Asbury Park, New Jersey.
