2. Rock and Roll, Hoochie Koo -- Rick Derringer
3. Life During Wartime - Talking Heads
4. Stone Cold Crazy - Queen
5. Supernaut - Black Sabbath
Could've chosen any number of Iommi's riffs but Supernaut is one of my favorites. I'm sure other folks will add plenty of his to this list.
One of my favorites from Iommi too.
6. Electric Funeral - Black Sabbath
Is the riff in Electric Funeral a heavy metal riff? I doubt it. That riff always sounded quirky to me.
Heavy metal can't be quirky?
