I use to go every year since like 95/96 but have not the pass 3 years as I have felt that Kevin Lyman has really changed the direction and for the most part the lineups suck. Yeah there might be good bands but you pay $50 to see a couple decent half hour sets. The only band I want to see that is not touring Toronto within the next little while is Westbound Train but I will not buy a ticket just for them.
However, to anyone that is going I recommend watching the Gallows as their new album is great and their live show energy dominates almost anyone. I saw them last year at the Mod Club and it was crazy!
