In two weeks well known Apollo Brown drops an instrumental Soundtrack called Thirty Eight. In advance you guys can download three of the beats compiled to the EP Cigarette Burns. Download is free! Beats are nice ... well, style is well known too.
In the description it says "The sound falls somewhere between the end of 70s heroin and the beginning of 80s crack ... " that's actually enough to give it a try and listen.
Not sure though if its really a OST for a real movie. Somebody should do some proper research on this!
