“Booka” is Austin percussionist, producer and Loud House Records label owner Booka Michel; the Flaming Geckos is the ad hoc collection of hotshot players he assembled to tackle the intriguing mélange of musical styles demanded by a movie about a Middle Eastern dictator who convalesces in Texas after his plane crashes on the Mexican border.
