Not long after delivering one of our favorite sets at Lollapalooza 2013, HAIM have unveiled the release date of their debut album. FINALLY!

Days Are Gone—the first full-length from the justifiably adored buzz band—comes out September 30 (Check out the cover art above). And—brace yourself—their debut album's title track was co-written with the insanely talented UK soul songstress Jessie Ware. Don't be surprised if that song—or even the whole album—is an instant classic.

The California sister trio have a perfect track record so far, from the endlessly listenable "Falling" to the glam-rock stop of their latest single "The Wire." And they're not just darlings of the indie crowd—they made a sizable national splash with their Letterman appearance and even impressed Jay Z enough that he brought them into the Roc Nation management fold.

We. Can't. Hardly. Wait. For. This. Album.
