A title like that befits something of equal simplicity and gusto, and “The Hair Song“‘s unhinged, tobacco-stained, porch-friendly swing is about as direct and meaty as Black Mountain get.

If there’s a live band that kicks it harder, louder, and with more abandon than Les Savy Fav, we haven’t heard of them. Fifteen years of art-punk flailing have culminated in “Let’s Get Out Of Here,” and the result is loose, precise, hopped up and perfect.

Apparently where Cut Copy are going is a place where classic rock radio plays all the time and tap water is actually lemonade.
