the first Neu! album (reissued in 01, but it looks out of print based on the prices i have seen)
all the early Sun City Girls (Torch and Horse Cock especially)
the first two Hanatarash albums (so jealous of Nefeli for finding a copy of Hanatarashi
)
Chance Meeting on a Dissecting Table by Nurse with Wound
Half Gentlemen Not Beasts and Charmed Life by Half Japanese
