Two new Katatonia CD (Album)

Opeth have better vocals and a darker overall feeling. I find them to be a better band than DT on Still Life, MAYH and half of Blackwater Park. Not counting Damnation that's my fav Opeth album though 'cause it doesn't suffer from their usual syndrome. Images & Words is definitely way better than newer Opeth though.
 
later dream theater is hit or miss for sure with exactly what you're talking about. a few good songs here and there but overall very annoying since they show potential once in a while and then go into endless wank mode anyway. Images & Words however has great structure I think, especially Pull Me Under and Metropolis. they're very technical but still manage to have a solid pace and good structure as full songs.
