Two of Alabama's most popular music acts are set to perform "Get Out the Vote" concerts on Saturday, Dec. 9, to support Doug Jones, the Democratic candidate for the U.S. Senate.

Jason Isbell, a Grammy-winning Americana artist from the Shoals, will play in Huntsville at Sidetracks Music Hall, 415 E. Church St., Suite #12. Doors open at 6 p.m.

St. Paul & the Broken Bones, a fast-rising soul-rock band from Birmingham, will appear at Birmingham's Boutwell Auditorium, 1930 Rev. Abraham Woods Jr. Blvd. Doors open at 7 p.m.

Admission to both shows is free, but those planning to attend are asked to RSVP online. Go here to RSVP for Isbell's show and here to RSVP for St. Paul & the Broken Bones.

The concerts have been organized by the Doug Jones for Senate Committee, rallying support for Jones before the Dec. 12 special election for the U.S. Senate. Jones is running a hotly contested race against Republican candidate Roy Moore, vying for a seat held for many years by Jeff Sessions.

No other information about the Dec. 9 shows was available, but Jones spread the word today via his Twitter account.
