Tinsley Ellis is driving around the country on what Alligator Records has dubbed his “Two Guitars and a Car” tour. And the next stop is Thursday at Stargazers Theatre.

That tour name comes from the fact that Ellis, a powerhouse electric blues/rock guitarist, is touring behind “Naked Truth,” his first acoustic album, carrying only the 1969 Martin D-35 acoustic guitar that his father gave him when he graduated from high school and a shiny 1937 National steel guitar.

“And I’ve got a trunkload of vinyl and CDs that I sell,” Ellis said. “They’re forgetting about that. But I definitely wanted to make sure I had a big enough trunk to carry a lot of vinyl and CDs around.”

Released in February when it immediately climbed the blues charts, “Naked Truth” is the 21st album of Ellis’s now-more-than-40-year career and the first he’s done entirely on acoustic guitars.

“I’ve got a bucket list of albums I want to make,” Ellis said. “One of them was certainly a live album and I did that in 2005. Another one on my bucket list was to do an all instrumental album. I did that in 2013. So this is my acoustic album and my acoustic tour.”

Playing acoustically, Ellis has learned, is different from hitting the stage with a band.

“It’s a little scary when I first go up there to play because I’m so used to going up there and being able to rely on the drum beat and the thumping bass, and now it’s just me,” Ellis said. “It’s the first time I’ve really been challenged musically in a long time and I think that’s a good thing.”

Over the course of a show, Ellis said, he’ll do the entirety of “Naked Truth,” mixing in songs like the Skip James-inspired “Windowpane” and the “Tallahassee Blues” and covers of Son House’s “Death Letter Blues” and Waters “Don’t Go No Further” with selections from throughout his career that take his blues-rock acoustic.

“It’s pretty high energy really, it’s not a mellow thing,” Ellis said of the acoustic show. “It’s just more personal. Another aspect of it that I really like, that people also like is I talk about how I wrote certain songs, give a little backstory to the songs and also talk about experiences from the road. I talk about maybe some old blues people that I crossed paths with and some cases played and intersperse for some stories.”
