"Hello, is it me you're looking for? 'Cause I wonder where you are, and I wonder what you do." With all apologies to Lionel Richie, showcasing midnight Wednesday at ACL Live at the Moody Theater, welcome to South by Southwest 2012. Herein resides the Chronicle's annual Music Festival supplement, with individual Picks & Sleepers, band lists, showcase picks, and interviews, Wednesday through Saturday. Y'all ready for this? Our man Chase Hoffberger is, writing about Richie thusly: "For me, he's Lucky Lionel, the man behind my parents' wedding song ('Three Times a Lady') and a likely contributor to my entrance into this silky smooth world a few years later. For all that and so much more, thanks be to Lionel Richie, who happens to have Tuskegee, his 10th album, readied for a late March release."
