It's a tie:
Labbatt's Hometown Bash
Three Days Grace, American Hi-Fi, Simple Plan, Korn, Nickelback
Comments: All were amazing, except American Hi-Fi, they were ok, but not great. The rest all put on great shows and sounded great.
MTV2 Campus Invasion Tour
Pepper Sands, The Weekend, Billy Talent, I Mother Earth
Comments: All were great, but Billy Talent and I Mother Earth are bands that everyone
should see live.
Godsmack w/ Mushroomhead and Alexisonfire
Comments: All were amazing, even though the crowd wasn't very receptive to Alexisonfire (great great band).
Scratching Post w/ Radio Holiday and Blue.Skies.At.War
Comments: Small venue, great bands, lots of fun.
Bands I wish I could have seen this year, but had to miss:
-I Mother Earth w/ Reason Disappears and The Salads (heard it was a great show)
-A Perfect Circle (I don't think I need to explain this one
