Did you see them on Americas got talent? That is the entire show. The songs they play are great classic rock songs and the are beating on buckets and random salvaged junk items but if I had paid for my tickets rather than getting them for free on seatfiller I would have been sorely disappointed.
Audience participation is high they hand you pots/pans and drum sticks and encouraged you to make as much noise as you can.
WEAR EARPLUGS! They sell them outside in the casino gift shop called Essentials for $2.50. My date and I left without any ear problems and we chuckled watching everyone else rubbing their ears as they were leaving. WEAR EARPLUGS!
Its a safe family friendly show and be sure to volunteer for the on stage act. You arent going to ever see these people again and I did have fun on stage. It will be something my GF will tease me about forever but I can always say I was there and you were to chicken to volunteer!
In summary; bring earplugs or buy on site, volunteer for the on stage act, get discounted tickets or you may leave disappointed with playing full retail.
