TV Sets: A synopsis of the musical guests to hit the talk show circuit this week.

“It’s about time,” David Letterman said of Alabama Shakes’ return to the “Late Show”. The group returned to the Ed Sullivan Theater in support of their upcoming album “Sound and Color”, out April 21.

Will Butler celebrated his album release day with a super-energetic performance of “Take My Side” on “The Late Show with David Letterman”.

This week The Afghan Whigs made their TV second appearance since releasing last year’s “Do To The Beast”, their first album in 16 years. After performing a blitzing version of “The Lottery”, the band rolled into a medley of “I Am Fire” and Fleetwood Mac’s “Tusk”.
