Gov’t Mule is hosting a special event in Atlanta at Masquerade Music Park on Saturday August 9. The group will perform two sets of music at the site’s outdoor stage, with support from Mike Gordon and Perpetual Groove (as a result, Perpetual Groove will no longer appear at the Trinumeral Festival on August 8). Then after the Mule wraps up, music will resume inside the Masquerade for a late show with Ivan Neville’s Dumpstaphunk (and presumably many guests from earlier in the day). Tickets to the late-show must purchased with a combo ticket, now on sale via Mule ticketing.
