Kendrick Lamar has been treating his fans with quite a few surprises leading up to the release of his album DAMN. on Friday and his Coachella closing set this Sunday.

After unveiling details such as title, artwork and track listing for the album earlier this week, the iTunes pre-order page has revealed another piece of information concerning the highly anticipated release. Joining Rihanna and U2 as guest features on the project will be a relatively unknown newcomer – Zacari.

The Los Angeles-based singer also took to Twitter to thank Kendrick for the opportunity to work together on his fourth studio album. He’s worked with Lamar’s TDE label mates Ab-Soul and Isaiah Rashad on their respective albums.

Take a look at the tweet and check out Zacari’s music below. Kendrick Lamar’s lead single for the album, “HUMBLE.,” can be heard here.

Yesterday, Kaytranada also revealed in a now-deleted tweet that he has an uncredited feature on the album (singing in autotune for the first time).
