The 39-year-old Chappelle has occasionally performed impromptu sets in comedy clubs. But he has largely avoided comedy and public life since abruptly leaving his hit Comedy Central series, "Chappelle's Show," in 2005.
Also on the bill are Flight of the Conchords, Hannibal Buress, Kristen Schaal and Al Madrigal.
