This is a band I really love. Some favourite releases:
Erpland, Arborescence, Strangeitude, Pungent Effulgent, Jurassic Shift
Erpland might be their strongest work, but the other ones are very interesting too. If you wanna know where their sound came from check out the firsts albums of a 70's band called Gong, specially the album 'You'. They are their musical parents and really rox.
If you like Ozrics sound, check out Hydria Spacefolk - Symbiosis. That album is just great and its in the vein of Ozrics. It was released in 2002 I think.
