Kylesa is a totally badass band who has evolved their sound into something which is almost a perfect mix of Baroness-esque progressive sludge / doom metal with a little bit of punk just for some extra flavor. Really good stuff. They are incredible live. If you haven't seen them yet, then you owe it to yourself to check them out. If that ain't possible, then at least buy yourself a copy of Static Tensions (their latest and best album yet).
If your show date also happens to include Bison B.C., then you are one lucky bastard, and you're crazy if you don't go. They are Canada's answer to High on Fire, and they rock balls as well.
Two awesome bands. Go see 'em.
