Monsters & Robots - The first album from him that I heard. Really diverse, ranging from Primus-y stuff, to dance-y stuff, to goofy horror movie-y stuff, to pretty acoustic stuff.
Thanatopsis - S/T: Like most of his collaborations with Travis Dickerson, (Population Override being his first) it's a bit more fluid and jammy/jazzy than a lot of his stuff, but unlike Population Override which was an intentionally retro sounding homage to some 70s stuff, Thanatopis are a lot more modern sounding.
Kaleidoscalp - Recorded using circuit bent equipment so it has a bizarre tone.
Crime Slunk Scene - Just a solid collection of songs.
Also, while Colma as a whole is just okay, Big Sur Moon is probably my favorite song of his.
