The attached video is basically nothing special, the name "Street documentary" is perhaps a bit exaggerated, but the DVD like me anyway. Completely without Kollegah, for 4 bouncer that tell a bit of nightlife, look sympathetic basically all and so convey some wisdom ("Respect is something you against every man must have" or "A mother cries no tears, a mother cries blood when her son what happens ").
A bit like the misleading name "Jewel Case" be. This is a normal CD case basically. For more information on Wikipedia.
