Dave Chappelle apparently is back in action after several years of being off the grid post the success of his “Chappelle’s Show.” First, he popped up on The Tonight Show Starring Jimmy Fallon in early June (where he set the record straight about going to Africa and coming back.) He made an appearance at the Essence Music Fest this past summer in New Orleans. He was in residency at Radio City Music Hall and now, he’s headlining Common’s September 21 Aahh Fest, which was recently relocated from the South Side’s Jackson Park to the West Side’s Union Park.

This is a major coup for Common as the last time we saw Chappelle in any such festival capacity was in 2004’s “Block Party,” which is now considered a comedy classic DVD filmed in Brooklyn.

Aahh Fest also looks to have a hefty lineup, with acts including Jay Electronica, De La Soul, Lupe Fiasco, MC Lyte and Lil Herb.  An “early show” will be curated by Rhymefest and includes Diggy Simmons (the rising star son of Rev. Run from Run DMC.)  The Aahh Fest organizers earlier this year announced a joint youth job initiative. Proceeds from the fest are expected to benefit the Common Ground Foundation, Donda’s House and Arts Education in Chicago Public Schools.

Chappelle, who is famously private, actually talked with Revolt TV about his comeback. Mostly, he seems to be doing it for the fans. Tickets for the Aahh Fest are $60 at clubtix.com.
