Paula Nelson shares a last name with her father, Willie, but she has a niche all her own, mixing blues, jazz, country, and rock with a little yodel for an infectious sound that’s pure Paula. She’s surprisingly also known for her stunt and martial arts work. Nelson and the band tour Texas performing cuts off her February release, the sultry, no-nonsense Lucky 13. Free, 6:30pm, County Line, 10101 Hwy. I-10 W., (210) 641-1998.
