Thirlwell's music—released under his various project names of Foetus , Wiseblood , Steroid Maximus , Baby Zizanie, Manorexia and others—includes elements of 20th century classical music , noise , big band , Americana , jazz , punk rock , African and Cuban percussion, and epic/horror film soundtracks. Much of Thirlwell's aural output is built on a percussive, rock music-type structure, though to call it rock music would be inaccurate. His music employs elements of many genres: with an often frenzied aesthetic, Thirlwell's music combines percussion, strings, distortion, brass, electric guitars, electronic sounds and voice. Recurring lyrical themes include destruction, persecution, anxiety, abuse, incest, masochism, angst, self-destruction, self-abuse, lust, prejudice, murder, failure and machismo, often expressed using American colloquialism and black humour .
The least noticable part is played by Jim and frankly I have trouble figuring out exactly what is coming from his laptop, but it''s unimportant. The whole thing is easily enthralling enough to pop me out of my Brooklyn Beer induced premature semi-slumber and raise the hairs on my neck. It''s not horror music, but it is subcutaneous and it is impressive in its execution to the level that makes you sick and delirious with awe. It rolls and changes and surprises you. It is a show that finishes with you immediately walking up to buy a CD despite knowing that there is no way it can recreate what you just witnessed. It is one of those rare shows that makes you feel exceptionally lucky to be in a certain place at a certain time.
