Query: Lots of prog moves but vocalist is horrible

Three things here:1) The music is not half-bad prog metal with decent keys and somewhat lacking guitar work.2) Compositionally, there's too much going on. These guys want to be considered prog so badly, they do not know when to can the scale/tempo changes in favor of memorable melodies.3) Vocal lines are very limited, largely due to the vocalist's severe lack of talent. This guy has a below average voice and can't hit a note at point blank with double-barreled shotgun. Simply terrible.Summary: Try again guys and get rid of the crappy singer. If the talent pool in Hungary is that dry, just put out instrumental albums.
