I don't think a day has gone by this week without some content from Reflection Eternal, so no need to stop now. Last night, Kweli and Hi-Tek were guests on Late Night with Jimmy Fallon. Above, check out their performance of "Ballad of The Black Gold" with some help from The Roots crew. RE also sat in with the band throughout the show and performed with them inbetween guests, so check out the full episode here. As if that wasn't enough, Kweli and Jimmy also held a live ustream last night – check that out after the jump. These brothas are clearly working hard, make sure to support their latest album, Revolutions Per Minute.
