As tens of thousands gathered at Chiba Marine Stadium to experience Summer Sonic headliner Stevie Wonder, Shunsuke Yano was preparing for his own show on the much smaller River Side Garden stage nearby.

On stage the Japanese rapper joked about the legend next door: "Why the heck did you choose to come here when Stevie's over there? We have to show our guest some hospitality!"

The crowd laughed; it was one of many laughs Yano, better known as Chinza Dopeness, got that night. At points you might have thought you were watching a comedian instead of a rapper.
