If I see a gig for a band I have never heard of in the street press, my first port of call is MySpace, for that is where any little known band that is looking for an audience will have their songs and videos displayed for all to savour.
Last year for example, I discovered Patrick Wolf and Wolf and Cub. Just add Wolfmother and you have a real pack going, though Wolfmother are a bit mainstream for my tastes. They do have a couple of good songs whereas Patrick Wolf and Wolf and Cub have whole albums of excitement and they are wild on stage.
As I have nothing to offer in this vein, I have left my MySpace site to rot.
