Folk singer Langhorne Slim performs the song "Restless" tonight on "The Late Show with David Letterman."

Slim, whose real name is Sean Scolnick, features drummer and former Milwaukeean Malachi DeLorenzo in his band. DeLorenzo is the son of Victor DeLorenzo, who was the drummer for the Violent Femmes and active member of the now-defunct Theatre X.

"The Late Show with David Letterman" airs at 10:30 p.m. on CBS.

Here is Julie Lawrence's 2006 brief about Slim.
