If you happen to see Champagne Champagne you will never forget their name. They chant it in every song and try, with less success as the set goes on, to get the audience to chant it too. You will remember their name on your death bed if you see them. They are, I suppose, a hip hop band with 80s and 90s references thrown in; songs about Molly Ringwald appear and they have a tune where they mix in part of Sonic Youth's Bull in the Heather (the additional lyrics for that song, if I recall correctly, were something about "sucking my dick). They mention dicks and fuck, fuckers, etc with frequency. If it had been 1977 I would have been shocked, SHOCKED I tell you.
BUT they are energetic and engaging and, I bet, judging from the finale they joined in with Starfucker, that if it were more than a trio they would feed of the extra energy. They need to have a big ass band with a horn section. Buy their music so they can afford that, ok?
And this is all about vibe. One minute you are thinking "Bright Eyes!" and the next "lo-fi dance" and the one after that you forget because you are hopping up and down and humming to yourself.
