first off let me explain what S.I.N Army is.... S.I.N stands for Safety In Numbers... basically its a collective of MC's, producers and crews... mr manage is the head man of it and brought it all togeather members consist of heas like, manage, possesed, stig, lynxeyed(wha's his face and precise), syanyde and many many more. this video is mr manage and i forget the other guys name, but its like the sin army anthem type track, basically these mans are smashing it for hip hop over here right now, and this collective is DEADLY AS FUCK cos it consists of probably the best MC's in the entire country... definately worth a check of the video, also at the end of it they have footage from making the video n shit like that aswell... enjoy!
