Kendrick Lamar hopped on Twitter this afternoon to lace his fans with a brand new song called "The Heart Pt. 3 (Will You Let It Die?)" featuring TDE artists Ab-Soul and Jay Rock. This will not be on his upcoming album good kid, m.A.A.d city, which drops this Monday, October 22. The song is produced by TDE's in-house producer Tae Beast, and mixed by TDE's engineer extraordinaire Ali. Yup, he kept it all in the family for this one. Listen below.

UPDATE. Apparently, this song was recorded last night, October 19, in Las Vegas. Awesome.
