Beautiful new track from BJ The Chicago Kid and Kendrick Lamar. Everyone’s heard of Kendrick, but if you’re a fan of Section.80 (and God help you if you aren’t..), you should be familiar with the first name as well. BJ The Chicago Kid is featured on Kendrick’s “Kush & Corinthians,” and that wasn’t the only joint track that could’ve potentially appeared on the best hip-hop album of 2011. The two paired up for “His Pain,” an emotional, soulful track produced by Sounwave, and it made an advance copy of Section.80 but not the retail version that hit iTunes.

Fortunately, the track has found a home and surfaced on the interweb as a result. “His Pain” will appear on BJ The Chicago Kid’s Pineapple Now-Laters, which is set to drop on Valentine’s Day.
