Greatest Guitar Riff

[Devourment]

Perhaps the riff on The Call of Ktulu by Metallica, it's the one quite into the song. There is use palm muting in it it is done & then gradually gets a bit higher... I don't know the time though.

[Rostum]

The whole intro to "The way young lovers do." by Jeff Buckley. It's the Live at Sin-e legacy version. Truely amazing. But I'm sure he has some other amazing riffs too.

So many good guitarists out there, I could also name a lot from the Tea Party - Jeff Martin is a genious on the guitar, and on other instruments (i.e. sitar, oud, etc.) expecially when he uses a violin bow on his guitar in Save Me. xD That's awesome.
