Brittany Howard

The group debuted the song written and previously recorded by Jesse Lafser at its first live show in July. Now, they've put out a recording of it.

Howard appeared in ensemble performances of "Heaven Help Us All" and "What'd I Say."

The Alabama Shakes' performance was one of a few moments from the three-hour show that actually had the command to put viewers on the edge of their seats.

Howard recently won 'Billboard' Women in Music’s 2015 Powerhouse award, and she lived up to the honor with a stunning performance of "Joe" at the ceremony.

Batiste was joined by the likes of Mavis Staples, Alabama Shakes’ Brittany Howard, Ben Folds, members of Beirut and many more.

Just four months after Alabama Shakes released their second album, frontwoman Brittany Howard has dropped the debut from her no-nonsense rock side project.
