No argument here. Gen was but one part of something bigger, and definitely not the most musically gifted part... Probably the least musically gifted member of TG, if I'm being completely honest. What Gen did have is a larger than life presence and prominence as a conceptual artist.
Right now my top three albums from the extended universe would be
Horse Rotorvator,
Trance by Chris & Cosey and
Seven Songs by 23 Skidoo (co-produced by Gen and Sleazy). Not coincidentally, they have 0 songs written or sung by Gen.
I'd like to read Cosey's book, wasn't crazy about Gen's memoir either. What I'm really looking forward to read is a book about the synergy between Gen and William S. Burroughs called
The Geometry of Suffering. Even if it doesn't live up to the promise, it's one of those books that sound too intriguing to not read.
