Colonel Les Claypool’s Fearless Flying Frog Brigade (also known as The Les Claypool Frog Brigade) is a musical project with rotating personnel, led by American singer/bassist Les Claypool. The Frog Brigade was formed during a hiatus from Claypool’s main group Primus.

The original band was formed in summer 2000 and consisted of Claypool, Todd Huth (guitars, vocals), Jay Lane (drums), Jeff Chimenti (keyboards), Skerik (saxophone), and Eenor Wildeboar (guitars, cümbüş). Les Claypool has described their sound as, “It’s kind of a King Crimson meets Pink Floyd meets Frank Zappa
