I used to put together a monthly list of concerts/gigs in Edmonton, but it was just too time consuming (grad school is going to kick my butt this term).
I didn't think anyone noticed it's absence, but a friend did ask about it, so I thought instead of putting together a monthly list, I'd just give you the links and you can check the venues yourself on a regular/whatever basis. Feel free to leave more links in the comments section.
Trust me, it's better this way. Now you wont be subject to my weird taste in music!
Festival Place (Sherwood Park)
Horizon Stage (Spruce Grove)
Shell Theatre/Dow Centre (Fort Saskatchewan)
The Arden Theatre (St. Albert)
