During CNN’s coverage of this week’s Democratic National Convention, Jason Isbell could be heard sound checking in the background. Isbell and his backing band, The 400 Unit, were running through “Something More Than Free,” the title track to a 2015 Isbell album.

According to Variety, Isbell is set to perform tonight during the convention’s opening night, which will also include a speech from President Joe Biden.

Folk/rock musician Isbell, who grew up in Green Hill and Muscle Shoals and is a longtime Nashville-area resident, has won six Grammy Awards, including two this year. In addition to his singing, songwriting and guitar playing, Isbell is known for his left-leaning (OK, more than leaning) politics.

In addition to posting on his social media, Isbell has put his music where his political beliefs are before. In 2020, he posted on Twitter if Biden carried Georgia in the 2020 U.S. presidential election, he’d record an album covering songs by Georgia artists to raise funds for charity.

After Biden won Georgia, Isbell made good on his promise. In 2021, Isbell released “Georgia Blue,” which included his versions of songs by the likes of the Allman Brothers, James Brown, Gladys Knight and R.E.M.

In 2017, Isbell played a solo acoustic show at the since-shuttered SideTracks Music Hall in Huntsville to raised funds for Democrat Doug Jones’s campaign. He supported Jones again in 2020, with another fundraising solo show, this time at Birmingham’s Lyric Theatre.

Isbell’s next concert is set for Sept. 5 at Charlotte’s Ovens Auditorium. Before then, he’ll return to Huntsville for an Aug. 26 event at which he and fellow Alabama native and Grammy winner Brittany Howard will receive Alabama Humanities Fellows, the highest humanities honor bestowed in the state.

The Alabama Humanities Fellows event will center around a moderated, in-depth conversation between the two musicians. Howard and Isbell will also perform one song each. Muscle Shoals native and (Isbell’s former bandmate in Southern rock outfit Drive-By Truckers) Patterson Hood will present Howard and Isbell with their Fellows awards.
