I first heard this single yesterday, and the first thought that crossed my mind was that it was nice to hear a Passion Pit song that wasn't baringlyly in-my-face.
"Hey K" comes as one of a few uploads to lead singer Michael Angelakos' new YouTube Channel The Wishart Group.
According to Pitchfork:
New York-based Wishart Group has raised $250 million in funding, and will provide legal, educational, and healthcare services to artists; a mental health program will remain its primary focus.
So yeah, that's pretty cool.
