On Tuesday Kendrick Lamar will return with "i," the first single from his good kid, m.A.A.d city follow-up and while we don't know what Dot will sound like, MTV News was able to confirm the sample that the track was built around.

The Rahki-produced track borrows from the Isley Brothers' 1973 version of their soul hit "That Lady," a source confirmed to MTV News on Monday (September 22).

The song was also sampled by the Beastie Boys on their 1989 track "B-Boy Bouillabaisse" and by Charles Hamilton on "The Awkward Prequel" in 2009.

Last week, Lamar revealed the cover art for the single. The image depicts a member of the Bloods and a member of the Crips street gangs in unity.
