Sure, Canada has produced abominations like Celine Dion, Alanis Morisette, and Shania Twain. But they've also given us Rush and Triumph. And some middle-of-the-road artists like Sebastian Bach*, Bryan Adams, and Barenaked Ladies, who are hard to revile but haven't produced more than a decent song or two. I mean look at Bryan Adams. He had a couple of hits in the eighties with some passable pop songs and then completely shit the bed with everything starting with his contributions to the soundtrack to the Kevin Costner Robin Hood Parody.
Here are some Canucks who flew under the radar.
Killer Dwarfs - We Stand Alone
These guys are goofy, but it works.
Exciter - Violence and Force
Part of the thrash explosion of 1983, but never got any attention. Because they were from the land of the ice and snow. Eh.
Anvil - Metal on Metal
Apparently whoever posted this video couldn't find a clip that was performed in English. Even though the audio is in English, the band is clearly singing in Canadian, and that's why it's not synched up.
Annihilator - Syn. Kill 1
Much like Exciter, these guys had the chops but never got much publicity. Of the four bands this is the only one that's still going (as opposed to reunited). I think Jeff Waters kills and eats his band members after every tour, though.
*UPDATE: Dave rightfully pointed out that Jewel is, in fact, American, and therefore had to be replaced. So I had to find a different not-so-offensive artist from Canada. In reality, I like a lot of what Bach did with Skid Row (their Slave to the Grind album kicked serious ass), but then he did Gilmore Girls, so he gets demoted. That show sucked like Roseanne singing the national anthem sucked.
