so this jam is "Jump in the Pool" by Friendly Fires, an English band that were on the shortlist for the Mercury Music Prize, a British music award.
The video has some cool parts and some weird parts, like the synchronized swimming and close-ups of the singer and band, respectively. I like the song a lot though, kind of ethereal like M83 with some good and busy drumming. Pitchfork mentioned the song sounding like 10cc in the beginning, which is a pretty funny comparison -- new electro indie stuff to 70s AM soft rock. And the chorus is kind of strange: it's about a pool? But still, good stuff. Their other single "Paris" is a good one too.
They only have one album out so far, and here's their Myspace.
