Prima Donna has a kind of early Kinks-meets-Ramones rootsiness to their music, at least on their recent Bless this Mess (Acetate 7044). Then somehow a little John Lennon sneaks in there. Then not.
It's wall of power-chord guitars band liveliness with vocal harmonies and a slightly punkish lead vocalist. They do originals that make a serious attempt to be real songs, and pretty much succeed in that throughout.
It's pretty hard hitting power pop punk I guess. And it's pretty good.
