Personally, I can't get enough of these two bands. Both of them are featured on Aural Moon radio.
Magus is a US band that would appeal to fans of Yes and Porcupine Tree(Their CD, "The Garden", is my favorite. )The best way that I can describe Finland's Prime Mover is a little bit of Hatfield and the North, Gong and Zappa, yet they have their own identity! They have a great album out called "Drivkraft.")Here are their links. If you like them, request their songs!
