Dredg is my favorite non-metal band.
I don't care what anyone says. Give dredg all the shit you want. I've seen, met and hung out with Dredg 3 times in the last year and half. They are the 4 coolest musicans I'll ever met. And their bassist, Drew, is a pure Metal head. He's just as big of Iced Earth fan as I am.
That said El Cielo is my 2nd favorite album of all time, right behind Devn Townsend's Terria. And The Canyon Behind her is my 2nd favorite song, just behind Dream Theater's A Change Of Seasons.
