Edward Sharpe and the Magnetic Zero will appear on “Late Show with David Letterman” on July 24 and “Conan” on July 31.

The Late Show will feature guest Jason Sudeikis. The Zeros first  appeared on Letterman on Sept. 4, 2009, when they sang “Home.”

“It was their network television debut,” Letterman joked, as he pointed to the band, “And it looks like a pretty good turnout.”

The band also appeared on The Late Show on Thursday, May 10, 2012 to promote their album, Here, which was released on May 29, 2012. The Zeroes sang “Man on Fire.”

“Loose-limbed frontman Alex Ebert led his band through the gospel-tinged tune, looking a bit bewildered but sounding warm and soulful,” RollingStone.com wrote.
