There is a Japanese based band called Ruins who are sort of like Magma except that they are a drum/base duo.Lots of insane noise and crazy vocals.
Tzomborgha is one of their albums to check out
Also Hawkwind and a lot of Frank Zappas work is prog based and as Hanoi Cheyenne said their is tons of great Krautrock stuff out there like Neu and Ash Ra Tempel.
