Here's a shot of the outdoor auto sound area outside of the BITEC convention center during the 2007 Bangkok International Motor Show. It was shot with my SLR which had some old grainy film in it and the light levels were pretty low so it's not the greatest. But you can get the idea of the setup. There's a big area of modified cards with huge stereo systems and the coyote dancers dance on top. They have a stage with a DJ in the back by Rocket Sound and dancers do a show up there, too. Hordes of guys crowd around during the dancing.
