Halley Elwell

4 p.m. Sunday.  South Parish Congregational Church, 9 Church St., Augusta, $10. halleyelwellmusic.com.

Mainer, singer-songwriter and pianist Halley Elwell’s new album is called “Spontaneous Mutation.” She hosts a podcast with the same name. The album opens with the piano song “Anomaly 1,” which introduces the listener to Elwell’s story. Elwell has a genetic condition called neurofibromatosis, which, in her case, means her appearance is unusual. Thankfully, this hasn’t stopped her from pursuing music and performing in public.

Her voice is clear and strong, and her songwriting formidable. The album is a thoughtfully crafted synthesis of rock, folk and jazz. Tracks like the zippy “How Do I Do This,” the moody, jazzy “Dear Lucy” and a free-flowing cover of Tom Petty’s “Time To Move On” featuring Alisa Amador, make for a polished collection of songs that harken back to the ‘7os singer-songwriter era that Elwell holds dear. Elwell and her Spontaneous Mutation band will be performing several songs from it during the album release show.

So far, there are seven episodes available of Elwell’s Spontaneous Mutation podcast. In one episode, Elwell’s guest is Amanda Leduc, author of “Disfigured: On Fairy Tales, Disability, and Making Spaces.”
