Everything Everything - Kemosabe

Sound: Indie Rock, Electronic-ish-kinda?, Falsetto Voice-kinda? 

How I Feel When Listening to It:

Everything Everything sounds like… everything. Even their Wiki has rock, pop, and R&B under the sound line. They float in and out of genre so effortlessly to make fun music.

Maybe you could say they are what would happen if you gave Alt-J cocaine and told them to go play music.
