Well, I've always liked their collabos with other producers, most notably, the one with Nottz...dude has heat...and their sounds mesh well. I got sick of hearing the same old chopped up soul vocal sample, sound of 9th. I thought it was dope on The Listening, but the novelty wore off, and I grew tired of the same sounding beats.
It will also be a good look for 9th, who's already branched out and done work on commercial projects...I wouldn't mind hearing a few 9th beats on an LB album, but they definitely needed the variety IMO.
