One of the things I really like about Bumpasonic (http://www.bumpasonic.com) is that we play some material that other bands do not. I see a ton of local bands that play Funky Music, Brick House, Brown Eyed Girl, etc. The good thing is that it is really easy to sub for bands in town. The bad thing is that EVERYONE is tired of most of those songs.
There will always be the people who only want songs that they have heard before. But, a good band can balance out the crowd pleasers with the unique. I like to think we do a good job of exposing audiences to some cool, obscure stuff. Come out and see if I am correct.
