"Hair Down" is the first single to be shared from SiR's new album Chasing Summer.

Speaking to Zane Lowe on his Apple Music Beats 1 show, SiR says of working with Kendrick Lamar, "He did exactly what he was supposed to do man. The song is about being confident in yourself, and i'm a huge fan. I ain't really gotta say it but you should've seen me in the session when he was recording his verse, I was sitting there like a kid."

"Hair Down" is out now. SiR's Chasing Summer album is yet to get a release date.
