Pro Era’s own, Joey Bada$$ recently let loose a previously unreleased freestyle from back when he was 16 to the interwebs for #PROERAweek. The young rapper is now back again with his team for a killer freestyle that was recorded over at the Billboard offices. The Pro Era crew showed off their talents on the mic and then went on to perform their Aprocalypse single “School High.” You can watch the performance and Billboard’s interview with Joey Bada$$ after the jump.
