"Alright, I know we just got started," J.C. Brooks said to the Rolling Stone Rock Room crowd at SXSW, "but you all still want a little more, right?" Brooks and his band, the Uptown Sound, then launched into "Want More," the title track off of the band's last record, thus answering Brooks's original question. Brooks and Co. did their darndest to rile up a festival crowd, at various points turning the mic into the audience for some crowd participation.
