Last month, Ghostface Killah producer (and Crate Diggers alum!) Adrian Younge shared some details on the rapper's latest album 12 Reasons to Die. Now, with Ghost's album available for streaming on NPR, the rapper is in full promotional mode, appearing on Late Night with Jimmy Fallon last night to perform his single "I Declare War" with the Roots (who are sticking with Fallon when he goes to The Tonight Show if you haven't heard).
