About a year ago when KRIT was in the Bay Area recording the "The Wuz Here Sessions" with Grillade, Berner reached out to KRIT's manager inquiring about beats for his "The White Album" LP. "Yoko" was one of them. KRIT actually produced a second song on "The White Album" that has Killa Kyleon on it.
The version on Berner's album only has KRIT and Wiz on it.
The story Berner told me about how Chris Brown got on it is that... they were working in the same studio in LA and Chris Brown walked by Berner's room and heard the beat, stopped in his room inquired about it, asked Berner to get on it and if he could put it on his upcoming mixtape. Berner obliged and thus, we have the "Yoko (Remix)". He also said that Chris is a big fan of KRIT's and was even more excited to do the record once he found out KRIT produced it.
