Thing is, Dream Theater is fantastic live, but I would never see them. John Petrucci has amazing improvisational skills, but his songs are whetted with staunch unemotion.

I still say it doesn't take a great guitar lick to make an intense song. Some of the most groin-grabbingly intense stuff I heard are purely vocal performances.

anything by Lightning Bolt

I dont know if its the most intense song but l'via l'viaquez by the mars volta has some pretty enjoyable intense parts

If i had to choose one it would be Megaghost.

i dont know, Dead Cowboy is pretty incredible, as is 2 Morro Morro Land... and Birdy... i think Hypermagic Mountain would definetly be the most intense album i own lol

Also adding,

In This River - Black Label Society

no pity for a coward - suicide silence
hey john whats your name again - the devil wears Prada
bleeding mascara - atreyu
medusa/black and blue/pray for plagues - bring me the horizon

<3 metal =]

"2 Morro Morro Land" kicks ass!

speaking of cowboy, the song Entombment of a Machine by Job for a Cowboy is sick.
