Doublepost for awesome bands I recently discovered or re-downloaded:
Diablo Swing Orchestra - Balrog Boogie
This is what happens when a bunch of guys who are multi-instrumentalists and ridiculously talented play a blend of swing, orchestral/opera and metal. Mindblowingly amazing.
Earth - Ouroboros is Broken
http://ca.youtube.com/watch?v=WrclNyck6HYCool Drone Doom band. Their older stuff is more real drone, and their newer stuff, like this, is flavored with some weird country guitar style, despite the fact that it's still sludgy and slow as fuck. Definitely a weird band, lol.
Earth - Engine of Doom
http://ca.youtube.com/watch?v=qcLic3qg-90&feature=relatedThis gives you an idea of how weird they can be in their newer stuff.
Polkadot Cadaver - Chloroform Girl
Wicked band, the successor of Dog Fashion Disco, and just as wicked.
Mushroomhead Save Us & Embrace The Ending
http://ca.youtube.com/watch?v=ksPgKn3XWy4Mushroomhead supposedly originated the idea of using masks, and has had an off and on rivalry with slipknot because of it, but they are NOTHING like slipknot musically. Not to mention their masks are cooler than slipknot's. Jason Popson (one of the vocalists) is awesome (I'm not sure if he songs on that song or not, though, not sure which album it's on).
The Alter Boys - Famine Ghost
http://ca.youtube.com/watch?v=5M_FUeJsDY8Another Jason Popson project, wicked stuff. Listen to the whole track, because it has some weird sections, like a surf rock/jazz breakdown with spoken vocals. Not to be confused with all the christian music that comes up on youtube.
Dog Fashion Disco - Acid Memoirs
http://ca.youtube.com/watch?v=PQFMY9cyzGo&feature=relatedThe name says it all, this is a humorous song about a first acid trip. If you like Mr. Bungle or any of that weird stuff, this is something you'll definitely love.
Mr. Bungle- Pink Cigarette
http://ca.youtube.com/watch?v=TwWQYg7aS5o&feature=PlayList&p=71CDDB23C374CE45&playnext=1&index=5Ok, this is a fan made video, but honestly, I am REALLY impressed. Without having heard this song before, I'd have to say that the video fits perfectly, and it was well done, unlike 99% of the fanmade stuff on youtube. Props to the guy who made it.
I've got more, but I'm getting tired, so I'll leave it at this.
