Bachman Turner Overdrive - "Not Fragile"

Riffmas third offering: One of rock's official diss tracks and the first verified (ex) Mormon to make this list. 

Carnivore - 5 Billion Dead

There's this part on "World Wars III & IV" where Pete just wails "WE HATE THIS PLANET!" and it's the most nihilistic thing you've ever heard in your life. "5 Billion Dead" is the post-coital cigarette to that sentiment. The vivid world of Carnivore, all mutants and warheads and Mad Max costumes and shit, snarling and incoherent, cruelly silenced by nuclear democracy. The riff plays us out, a single ribbon of smoke curls upwards and then black. Just black. 

UFO - Prince Kajuku

Thee DDZ Premiere RIFFmas offering: British HARD rock from just after Vietnam and before that German gee-tar god got thrown in the mix. The lil flurry at 1:04 is my absolute fav, but the whole record is chock full of these little bastards. Happy riffing!
