How about good ol' RUSH ?
And "kings of indie", Arcade Fire?
It's good to hear about bands or singers being known outside of the country. I mean, how much Celine Dion can we take?
My favourite new group is a Canadian super group, Crash Karma. Featuring a couple friends of mine, Jeff Burrows of The Tea Party and Mike Turner of Our Lady Peace. They have Evan of I Mother Earth singing for them. If you get a chance, check them out, they'll be winning an award in the upcoming Juno awards for sure.
My love is the Canadian Music festivals. Minidosa rock party in Manitoba is sweet.. pemberton in BC (and of course SHAMBALA if your into Electronic madness) ness creek in Saskatchewan is super fun.
