Query: i had enough...

the first thing i heard from akerfeldt was his vocals in Katatonia's brave murder day. i was impressed by his powerful yet desperate voice (the best growling vocals ever!!!), so when i discovered his band opeth, i bought orchid, morningrise and MAYH without hearing any of it... so this review (and the star)goes for those 3 works. in either of those works akerfeldt's voice has the magnificent, despair and greatness of brave murder day... so that was the beginning of the end.I don't care if opeth's music is complex and delivered by great musicians, for me sounds very artificial and bored... opeth reflects virtuosity but that's not enough, they lacks attitude and soul.When i have insomnia i put opeth in my cd player...
