It's not the kinda stuff you get into on the first listen, they are very technical and not unlike a trippy Rush at times. The vocalist is even weird and high-pitched like Geddy Lee.
A friend of mine called their music prog rock on speed, even if afaik they don't do drugs anymore. Lots of substance as you get used to them.
