How long have P. Blackk and J. Rawls been working on Contemporary Nostalgia, the album they drop Dec. 30? "I think it's safe to say it's officially spring," Blackk adlibs at the outset of "Submuloc Fo Ytic 2.5" before blaming Fabrashay A's contagion for the snot accumulating in his throat. In some genres, three seasons might not be that long between recording and release, but for 2012 hip-hop it's an eternity. That tells me this record is going to be the farthest thing from a mixtape castoff. My excitement is affirmed watching these three longtime pals bugging out and repping their city over Rawls' cloudy-day-in-the-park beat.
