Steamboat Springs — Folk-pop singer Lucinda Williams performs tonight and Susan Tedeschi will perform Saturday as Steamboat’s free concert series continues.

Double Trouble will conclude the string of shows Aug. 22.

Williams plays her free performance at 5:30 p.m. at Headwall at the base of Mount Werner. Her musical influences range from Loretta Lynn to Jimi Hendrix, but her sound is a blend of country and folk with a religious message sometimes mixed in.

Williams’ most recent album is “Essence.”

After countless albums produced in the 1980s, it wasn’t until her self-titled album was released that people began noticing Williams. She won a songwriting Grammy for “Passionate Kisses” from that album, and “Car Wheels on a Gravel Road” six years later won her a second Grammy.

“Both Lucinda and Susan represent a new wave of female artists,” said John Waldman, co-owner of Great Knight Productions.

“They’re not the same style but have strong abilities in what they both do.”

Tedeschi’s free performance is at 6 p.m. Saturday at Howelsen Hill.

Among the many blues artists in the world, all this Massachusetts-born artist needs is a little soul and profound influences to understand blues.

Her latest album “Just Won’t Burn” was released in 1998.

At the 2000 Grammys, she was a nominee for Best New Artist alongside such heavies as Kid Rock, Macy Gray, Britney Spears and Christina Aguilera.

While Tedeschi reaches out as a new star among women blues artists, Williams grabs the folk rock genre, Waldman said.

Waldman said he first looks at the style of music an artist encompasses and sees if that appeals to the community. Secondly, Waldman looks at the price range that an artist requires to perform and what the nonprofit series can afford.

Lastly, Waldman said much depends on the availability and routing of the artists’ tours.

Double Trouble performs its free concert at 5:30 p.m. Aug. 22 at Headwall at the base of Mount Werner.
