Query: Grow up, Kids

Just saw this band play in the D.C. area, and was thoroughly annoyed. I've never seen a band so full of themselves. They do have some talent as musicians, but they're too busy doing stage kicks and exchanging glances with 14 year old groupies to write a decent song.The genesis of a good band is there, but something has gone horribly awry. To their credit, they are a bunch of youngsters but they have a lot of growing up to do musically and lyrically.
