I wouldn't pay $30 for that show. I like the Roots but that's the only act I see worth paying for and they're not getting $30 from me. moe. charges about $30 for their shows and they were FREE at Riverside Park. They should consider changing the name if it is all R&B and Hip-Hop acts. Not much variety there.
get a lot more sponsors.. and I hate to say it but beer vendors make a ton of money on these things. Unfortunately the hip hop crowd is relatively young.
