“Hey K” was released on February 19th, 2017, and is a part of Passion Pit’s “Tremendous Sea of Love.” It is the fifth song in a series of songs that were posted to the YouTube channel “The Wishart Group” within the span of one week. The Wishart Group is a new company for artist support founded by frontman Michael Angelakos.

Unlike the other songs in the series, Passion Pit frontman Michael Angelakos teased the song by tweeting a part of its lyrics three hours prior to its release.

“K” refers to Angelakos’s former spouse, Kristina Mucci, who was the subject of Gossamer’s “On My Way.” Angelakos indirectly confirmed this with a tweet referencing Kristina as “K”
