OK Go, the band that is better known for making viral music videos than it is for making music, has a new audience: preschoolers. Check out the group’s “Sesame Street” music video and song about the primary colors:

This isn’t the band’s first time dipping its toes into kids’ entertainment: They collaborated with “The Muppets” in advance of the 2011 film, covering the theme song of “The Muppet Show.”

It’s also not the first time, the guys have worn primary colors, as writer Chis Klimek noted in his review of OK Go’s performance at the Kennedy Center last June.
