Went to the show last night. Believe it or not I am actually at work now..... Great show, sounded great (even in our crappy old auditorium), my ears are still ringing.
I saw 7dust last year (or year before). Big fan. They didn't do "Black" though and that was disappointing.
I've never heard of the first band and I don't think I liked the second band but I know I wouldn't want to tell anyone that I saw Disturbed.
Skindred is from the UK. They played a lot of their music off their 04 album on the radio, kind of a metal/reggae mix, interesting and good. There was some political messages imbedded, but not bad. Maybe rage against the machine with an island flare.
