The Hardest Rocking Metal Power Trios?

i knew you were gay.

and I might as well get it out all at once.
Rush are really boring.
Led Zeppelin is really boring.
Jimi Hendrix doesn't interest me.
Early Judas Priest is decent, but doesn't excite me
Slayer's Hell Awaits is meh (planning on forcing that album on myself, so that may change)

One look at half the things that excite you makes me wonder why you think that way. Cartoon bands like Wintersun never did much for me; but you seem to like some good stuff.

Led Zeppelin's first two efforts imitated selected blues artists to the point of near plagiarism, however, they definitely became relevant come number 3.

Metal Blade Slayer is the only good one.

Rush is stupid in many ways, but the first album fucking rocks, along with selected tracks. I would definitely say I prefer YES.

I would recommend revisting Jimi Hendrix, and as for Priest; How the hell could you not be excited by a song like, say, Sinner? They definitely became a living comic book later, an often times enjoyable one, but man, in the 70's they were alarmingly relevant.

EDIT: Fuck, was this thread about Power Trios?

Big props to whoever mentioned Morbid Angel. I'll throw in Reverend Bizarre.
