Hmm. Not much I suppose.
The Vines (toured with incubus, so they were at the same show)
Three Days Grace (when they were actually good)
Nickleback (3DG, Staind and Nickleback toured together, so they were 3 in 1)
The Dresden Dolls
Patrizia (technically wasn't a concert, just this free thing at City Hall)
Only Sun (Lead singer though, whom toured with Regina)
Lead Astray (local screamo band, band memebers all attend my school except for the lead singer, he dropped out)
