“We’ll be bringing a different show this time,” says California-bred guitarist Debbie Davis, who’s getting ready for a four-month tour in support of her first instrumental album, Holdin’ Court. Like Bonnie Raitt, Davies is one of the few female guitarists to make it in the blues realm. “We have a lot more [women playing] than when I started out,” she says. “I’m always hoping to inspire women to pick up a guitar. There are a number of female guitar players coming up on the scene. It seems that the door is open for us to come out and play.” On this tour, you can expect to hear lots of music from Holdin’ Court, plus some songs by singer and harmonica player Robin Rogers, who’s backing up Davis and opens the show at 9 p.m. at the Winchester (12112 Madison Ave., 216.226.5681). Tickets: $15. — Ernest Barteldes
