that shit happens SOOOOOOOOOOO much with bay artists, and business in general unless it's a big ass tour. In 94, I had tickets to mary j blige and notorious big at great america, first mary j was the only one there, then she decided she didnt' want to perform...
in 2001, I went to the phoenix to see the luniz and digital underground, of course the luniz weren't there.
in 2002, I went to a free ashanti concert. Redman and Ja rule were supposed to be there, but of course just ashanti was there. It's not that I really wanted to see either of them, and it's not like i paid to get in, but still, why advertise that you're gonna be there if you aint?
