I saw sublime w/Rome last summer, it was a fantastic show. I know this is treason, but I prefer Rome to Brad live. Plus the band all just looked like they were having a blast playing live again.
I really wanted to see primus, but they aren't anywhere near NOVA/Dc.
And 40 bucks isn't bad, I saw Maiden for over 100 bucks, but got to be front and center the entire show. Saw Rush last month, that was 100 bucks for Eh seats but the few shows I go to are usually like my absolute favorite bands. I might go to 2 or 3 really big shows in a year.
Under 20 bucks, I'll see just about anything if I know some people going or like the band.
