Ok. So I went to myface or spacebook...whatever its called, and listened to a few of their songs. I then went to youtoob and watched a video thay had a link to. It aint bad. A good looking woman up front singing might have made it more interesting for sure. In my own personal world there is just too much music going on the world. A performing/recording "act" really.....and I mean this: REALLY needs to stand out. Really NEEDS to be exceptional. These guys you are pushing were decent imo. I think the ultimate bottom line is that as long as they are enjoying themselves and work their tulips of then they should do alright!
Best of luck to them.
