Sushi K rolls down the window. The decibel level quintuples in an instant. He stares at the crowd, five thousand potential market shares, young people with funkiness on their minds. They've never heard any music before that wasn't perfect. It's either studio-perfect digital sound from their CD players or performance-perfect fuzz-grunge from the best people in the business, the groups that have come to L.A. to make a name for themselves and have actually survived the gladiatorial combat environment of the clubs. Sushi K's face lights up with a combination of joy and terror. Now he actually has to go up there and do it. In front of the seething biomass.
