The band took the Rams Head Tavern stage Friday for three hours of jubilant, percussive music….. Their blend of African and South American sounds placed them worlds away from the other Hawaiian-shirted throngs. Cebar currently tours with two percussionists, Reggie Bordeaux and conguero Romero Beverly, and they joined bassist Patrick Patterson for beats that were more lively than heavy. With Cebar on guitar and Bob Jennings on saxophone, keyboards and accordion, the result was full-on, pan-ethnic party music. Whether with a palm-wine song from Sierra Leone’s SE Rogie, a reggae reinvention of “Second That Emotion” or Cebar’s own soul/jazz/rock-influenced songs, the Wisconsinites seemed to have gone south from the Cheese State to form their own Bourbon Street second-line parade. Cebar himself started slow and easy, with a( ……. )voice soon revealing itself to be a flexible and compelling instrument, particularly on his solo encores. The quiet eye at the center of this clamorous hurricane, he reveled more and more in the rhythms as the show progressed. During “Wasabi,” as Jennings pounded on the keys, the frontman performed a charming, idiosyncratic take on the Bus Stop, thrusting and hitching as his guitar, unneeded, dangled at his waist.
