She’s back!

After a three-year break between her most recent albums — “How Big, How Blue, How Beautiful” in 2015 and then “High as Hope” earlier this year —Florence Welch, that ethereal goddess of indie rock, has returned. And not just to record but to perform. Florence + the Machine, as Welch and her band are called, are on a tour that will bring her to Mohegan Sun Arena on Saturday.

Florence + the Machine usually give electric live shows. Welch skips and twirls across the stage, barefooted, as she wails her lyrics, full of life and fire. And her voice is an evocative tool. In my review of her 2012 concert at Mohegan Sun, I wrote, “Her throaty voice swirled like mist and then twisted and built into a hurricane. She whispered. She wailed. She created the aural equivalent of a swoon.”

Florence + the Machine, 7 p.m. Saturday, Mohegan Sun Arena; opening ac Grizzly Bear; $53.50-$93.50; 1-800-745-3000.
