Skratch Bastid has given us a very dope mashup of Bob Marley's "Get Up Stand Up" with War's "Slippin' Into Darkness". In Skratch's explanation of this mashup he explains how Bob wrote Get Up Stand Up based on a direct influence of "Slippin..." Bob expanded on the guitar riff he took from Slippin', so naturally these two songs work well together. Listen to the result below.
