Here's a 2.5-hour recording of Barnt and Rebolledo playing the Mayan Art Car at this year's Burning Man Festival. Rebo tells in the description: "… originally we wanted to have some back-to-back moments and some solo parts but we got so into it that we stuck together until the end for an almost twelve hour set…" The second part of the set (hopefully) comes soon. Meanwhile you should check out this little video here...
