if you manage to make it big on your own, without changing your views, or your sound for the record companys, thats fine, I say you managed to beat the system and didn't sell out. A good example (though others would argue) would be Generation X. However I'll give you another good example of selling out, and not even making it big.
The tour manager for The Casualties, gave me a call one time wanting to do a show in the DC/Balt area. However here is the catch. They wanted $4000, and the only two days they could play were a tues or weRAB show in the middle of Sept, and I would only have 3 weeks to promote. I basicly laughed at that, there was no way in hell I would give that type of cash to them, even if they could play a prime night like a friday or saturday. Not to mention that 3 weeks is way to little time to promote a show like that anyway.
I argued with her for about 15 minutes before finaly telling her she's flat out asking to much for a band thats not going to draw in this area. Her excuse was this "well, we managed to draw 500 during Holidays in the Sun" wich is bullshit because people come from all over the country to go to that EVENT, not just to see The Casualties. I also told her that I could get the Dropkick Murphys for less than they were asking up front, and I KNOW that people would come out for that, so why should I give you $4 grand up front? She couldn't give me a good answer. I finaly offered her $1000, and 20% of the door, said if the band had that much of a draw, than that would come out to about $4000, but I would not give them the money up front. She said no way, and I said later. They got some poor sucker in Roanoke to put up the money for a show down there, and he got taken seriously! The show barely broke $500, and the poor guy had to pay up the $3500 himself, wich put him out of promoting punk shows for nearly a year, effectively fucking up the small Roanoke punk scene.
Now this is The Casualties for you, this is a band that calls themselves "real punk rockers", yeah well guys I got news for you, your not close to being punk rock you postcard fucks! If they were real punks, they would have done the show for beer and a fair portion of the door. All about supporting your scene man. If you act like a rock star, and screw over your scene and don't give a damn, THATS when you have sold out!
