I actually went in early one night to listen to DC and to be honest they weren't bad, very young, inexperienced at playing to anything bigger than a bar, but they have some decent songs and they were trying I have to say. I don't know if they will ever be BJ big, or even say Matchbox 20 big, but I think given time they may well come up with some cool stuff.
I really don't think they were ready to open fora band like BJ.
But then again, you gotta learn somewhere.
