After a 1976 concert, a reporter asked Anne Wilson about her and her sister Nancy's made-up "lesbian love affair." The enraged songstress went to her hotel room and began writing the lyrics that would become "Barracuda," and the rest is history. With a career spanning four decades and more than 35 million records sold, the Seattle sister super-duo continues to write, produce and tour in support of new music. This go-round is for the newly released Red Velvet Car. Expect to hear plenty of classics like the aforementioned "Barracuda," with a slight focus on the new ones as well. They want fans to concentrate on the here and now. $20-$49.50. 7:30 p.m. Road Runner Mobile Amphitheatre, www.livenation.com.
