After somersaulting through a shallow puddle, the lead singer of Osaka's Vampillia stared intently at a nearby taco truck. As his band plowed through a noisy, violin-assisted song on the third afternoon of the South By Southwest (SXSW) Music Conference And Festival, he scaled the vehicle and screamed from the roof. The crowd cheered as he danced, all while dressed in tights patterned after the human muscular system. His stunt grabbed the attention of many people walking by the venue.
