Hey, corporate sponsorships aren't always a bad thing. Sometimes it leads to some pretty cool events, like the SOUTHERN COMFORT MUSIC EXPERIENCE, a free two-day festival brought to you by the whiskey manufacturer. Some of the top-flight bands playing MAY 20 include Cowboy Mouth, Ozomatli and Atlanta's own Family Force 5. MAY 21 brings the Flaming Lips, Big Star, De La Soul and the Gourds. If that lineup doesn't get you drunk, the panoply of alcohol and food booths will. Appropriately, only adults 21 and over can attend. See Vibes. Free. Sat., noon-11 p.m.; Sun., noon-10 p.m. Centennial Olympic Park, 265 Park Ave. West. www.southerncomfort.com.
