The connection between the Ex track RaRa Rap and RaRa Radio, the online radiostation, is that they both refer to the Dutch organization RaRa (Revolutionaire Anti-Racistische Actie). RaRa was a Dutch group of activists whose actions were described by the Dutch national security service as 'political violent activism'. RaRa was active from 1984 to 1993, but the group was never officially disbanded.
