Low Duo, a band made-up of two brothers: Adam and Leigh Greenwood.
They make a sort of melancholic music vaguely reminiscent of The xx and Radiohead. The instrumentation is fairly sparse and simplistic, and yet it's precisely this which gives the music a sort of primal, vital feel, with urgent rhythms like heartbeats, as well as the falsetto vocals intoning the desolate lyrics (like the should-be-cringey-but-just-about-works, "let me drown in the rain"). There are sudden crescendoes and diminuendos, both of which add to the intense dramatic feel of the otherwise nicely minimalist music.
Definitely worth listening to if you haven't already.
