You’ll enter the Upside Down when Philadelphia native Raheem Jarbo geeks out as Mega Ran (formerly Random) at this week’s Knocturnal, combining his love of gaming with his past life as a middle school teacher to create some of the more eclectic nerdcore since Kool Keith morphed into Elvis and got lost in space. If any of those references rocketed past you, come anyway. You’ll be signing up with Team Mega in a Philly phlash. For extra credit, download Ran’s latest LP, Extra Credit.
