I remember that phantom planet show. That's exactly what happened. Everyone only knew "California". I thought Ludacris was pretty cool though right after. I missed Talib Kweli last year. Oh well I heard there were some technical problems anyways.
Just did a quick little google search on shozoko and one article said ninja uniform was usually called shinobi shozoko. So I suppose they are sticking with the whole samurai/ warrior theme for Kobe.
