Vauxdvihl - To Dimension Logic
parts of this album are really genius, while others are quite cheesy. it's a shame. the first 3-5 songs are so great.
I agree that many many prog metal bands are awful. but there are some gems, like
Anacrusis - Screams And Whispers
Psychotic Waltz - A Social Grace / Into The Everflow
Waltz isn't exactly obscure, but maybe you haven't heard of them as they disbanded long ago...
