Brasstracks' For Those Who Know Pt. 2 is the highly-anticipated second edition to their 2017 album, For Those Who Know, following the project to revisit and close out on familiar themes to the production duo’s early work. Brasstracks—comprised of performers Ivan Jackson on trumpet (and pretty much everything else) and Conor Rayne on drums—is famously known for their contribution to Chance the Rapper’s “No Problem” beat, in addition to collaborations with Alexander Lewis, Khalid, S'natra, and Jay Prince. In a message to their fans on Instagram, they wrote: This is For Those Who Know—we sincerely hope you enjoy this project as we close this chapter, and move on to the next.
