The late 90's were a transitional time for both videogames and Hip Hop. The gangsta rap craze which made criminal behavior a selling point on a rapper's resume was starting to cool down, while in videogames, the same kind of antisocial content was just starting to heat up. The Beastie Boys and Jet Set Radio both existed in that tense space between the rebellious mischievousness and genuine sociopathy that largely defined late 90's pop culture, so it makes perfect sense to see them brought together here.
This Jet Ill Radio mash-up track by Psycosis combines the Jet Set Radio soundtrack (2000) with the Beatie Boys' Hello Nasty (1998). Some tracks a better than others, but fans of either source material would do well to check it out. The Mischievous Boy and Intergalactic mash-up is particularly charming. If you like what you hear, head back to Psycosis's channel for some heart warming Parappa the Rapper mash-ups. Jay-Z + Instructor Mooselini = Party Forever.
