Haim perform 'Forever' on Letterman

With “Falling” and now “Forever,” sisterly act Haim are on some other shit, nailing a strain of soulful, syncopated, and clean LA studio pop with just the right touch of fashion, finesse, and familial alchemy, and their fanbase has grown by degrees wich each of those modifiers. This is a band we can get behind, let alone one to watch, in both pure musical and also pure visual terms. As such, last night on Letterman was a proper showcase for their charms, and as such, they charmed.
