BRANDI CARLILE (pictured) headlines the current "You Oughta Know" tour, created by VH1. The Indigo Girls-approved singer/songwriter is supporting her album The Story. A Fine Frenzy's Alison Sudol will open the Tues., SEPT. 25 show with music from One Cell in the Sea, her excellent debut. Both offer moody, intelligent atmospherics, interesting characters, first-rate musicianship and a refreshing diversion from most of the current crop of derivative disappointments that masquerade as modern music. $20. 8 p.m. The Roxy, 3110 Roswell Road. 404-233-7699. www.ticketmaster.com.
