Lou Ann Barton (born February 17, 1954) is an American blues singer based in Austin, Texas since the 1970s.

[1] AllMusic noted that "The grace, poise, and confidence she projects on-stage is part of a long tradition for women blues singers".

[1] In late September 1977 Barton joined a new Austin blues group, Triple Threat Revue, with Stevie Ray Vaughan and W. C.

[2] Her next release was the 1989 album Read My Lips for the Austin-based Antone's Records,[2] a return to her blues roots that featured versions of songs made famous by Slim Harpo, Hank Ballard and Wanda Jackson, among others.

[citation needed] Through 2018 Barton continued to perform in Austin, and elsewhere, sometimes "[b]acked by Derek O'Brien, Denny Freeman, Scott Nelson, & Jay Moeller", sometimes with Sue Foley.
