There's Margaret Doll Rod , still performing under that name , with a guitar/drums set up , often Bluesier than she was with "Dem Dell Rods" as Andre called 'em.
Honkitonkioke , From NYC (?) . She sings Country standards , with an overhead projector , using drawings on clear plastic like puppets....You'd have to see it. Words fail me.
Did anyone mention the Late , Great Cordell Jackson ? The first woman to own and operate her own studio , before Bonnie Guitar. Very seldom played with a band at all. Her solo live show was a wonder to behold. Fiery , fiercely independent and FUN. GREAT INSTRUMENTALIST , SINGER AND SONGWRITER , And , a great lady , besides....Look for "Live in Chicago" on Bugout Records.
Barbara Lynn sometimes plays solo . Do I have to tell you it's great ?
There's more. Gotta think of 'em. You're asking a man to THINK? Ohhhh, it's gonna be a long night.
