Nice, dreamy name for a musical duo, don't you think? There isn't much I can say that their name doesn't tell you. :)
Out of Baltimore, Maryland, and out of the gate close to 10 years ago; they've met with positive reviews, but garnered more visibility and that thing we call commercial success only recently (that is, the past few years). Four studio albums in all, it was the third one that seemed to put them on the map (and for many fans, will be hard to top), "Teen Dream". Two tracks you may have heard are "Zebra" and "Walk in the Park."
I'll say this up front: I like their setup, but they're not game changers, and they don't offer much variety in their music. Not a criticism, but the reason why some people may say, if you have one CD, you have them all. I don't necessarily agree with that, but I can understand the sentiment. I get a little Mazzy Star out of them, maybe some Lush, too (thanks to Polar).
Their most recent album, "Bloom" was released in 2012, and ended up on quite a few "bests" lists (FWIW), but even their fans were surprised. "Bloom" is a concept album, and should be listened to in entirety, as it's a "unified vision of the world" --- not sure about that, but whatever.
The good news / bad news about lots of electronic pop / indie / ambient music is that ultimately, the differences are very subjective, as are the reasons you may be drawn to this style of music, or a band like Beach House in particular. It's like making a new friend: sometimes, you just hit it off.
