Blather, rinse, repeat

First of all, that was ONE concert out of 15 years of work in HIV prevention and awareness. The concert was not a benefit, it was to raise awareness in the Caribbean community, where HIV infection rates are on the rise. The artists were all working for free.

Second of all, the concert was cancelled. It never happened.

It doesn't even sound from your comment like you knew who the band was, or what their lyrics were all about, or any other information. It might be a good idea next time to do some research before you slander a respected non-profit organization.
