Do It Today: Dining Out for Life and mucho music — from jazz jams to Cornmeal's electro-acoustic bluegrass and the Tampa Bay Symphony

a few special guests will be dropping by to lend their vocal stylings to the tunes, too. americanstage.org. April 29-May 15, 10:30 p.m. Thurs.-Sat., American Stage, St. Petersburg, "pay what you can" at the door, $20 in advance.

Chicago five-piece Cornmeal – made up of drums, guitar, banjo, upright bass and fiddle – plays a fast-dashing and furiously fun style of progressive electro-acoustic bluegrass marked by rich three-part vocal harmonies and Americana, folk and jammy roots rock tendencies. This past March, Cornmeal released Live in Chicago, IL Vol. I, an album that captures the contagious energy the band delivers in a live setting while showcasing their talents and ability to improvise, like in the 14-minute scorcher, “When the World’s Got You Down,” an uplifting propulsive number with fiery guitar and fiddle solos, the two instruments vying for ultimate sonic supremacy in an extended stretch of refreshingly intense jamming. Thurs., April 29, Orpheum, Ybor City, myspace.com/theorpheum. --Leilani Polk
