Kylie Minogue & Towa Tei - Sometime Samurai -Featuring GREY and GKAE?

I found this video on 12oz. The song is pretty good because Kylie always comes correct. But the meat and potatoes of this video are the artiststhat are featured in it. Looks like some of my favorites in San Francisco writing on walls and riding on vespas. Cool but very strange. Who paid for this? It's actually shot really well. So many questions...
