TV cooking queen Rachael Ray is making her annual presence at South By Southwest bigger and better this year. And public.

Ray's third annual Feedback Festival, slated for March 20, is moving to its largest venue yet -- Stubb's BBQ -- with 18 bands playing four stages; Daytrotter.com will be recording performances on one of them. The show, co-sponsored by Mr. & Mrs. T drink mix maker, will be free and open to the public for the first time, and the bash will be filmed for subsequent airing on Ray's syndicated TV show.
