When he wasn’t battling trolls on Twitter, Talib Kweli was quietly gearing up to release music. Early Wednesday morning, Kweli released Train of Thought: Lost Lyrics, Rare Releases & Beautiful B-Sides, Vol. 1, a 10-track compilation of rarities and B sides with guest appearances from Killer Mike, Common, Mos Def and Kanye West.

Kweli hasn’t released music since 2013, but Train of Thought includes production from longtime collaborators DJ Quik and Hi-Tek.

The album is now available to download for $12 at Kweli’s website, KweliClub.com.
