With a vocal range that seems to reach from a Johnny Cash hangover moan to one of those Alvin & the Chipmunks stratospheric tenors, singer-songwriter Martin Sexton can definitely open his throat and amaze.

He's also got a fine sense of dynamics and a craftsman's appreciation of the possibilities of pop songwriting. His latest recording, the four-song EP "20/20 Vision," made during COVID lockdown, is a defiant and melodic document about making the most of hard times and spending time doing simple things with family and loved ones.

With similar optimism, Sexton is on an ambitious tour that brings him to the Katharine Hepburn Cultural Arts Center Friday. He'll introduce the material from "20/20 Vision" as well as provide a broad and loving retrospective of long career.

Martin Sexton, 8 p.m. Friday, Katharine Hepburn Cultural Arts Center, 300 Main St., Old Saybrook; Chris Trapper opens the show; $65; thekate.org, (860) 510-0453.
