Apparently where Cut Copy are going is a place where classic rock radio plays all the time and tap water is actually lemonade. This MP3–the first hint of their new, as-yet-unfinished record–is pure flower child pop: rag tag drums, tie-dye melody and those keyboards from “Baba O’Riley” that sound like they could fill the sky.

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. These dudes are talented nutjobs and they should never, ever change.

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. The Vancouver quintet’s new album, Wilderness Heart, is due out September 4 through Jagjaguwar. It has a shark on the cover, which obviously symbolizes its face-eating powers.
