When blues guitarist Tab Benoit takes his fever for the Louisiana Bayou to the folks at the Bamboo Room on Saturday night, he will do so with blues-rockers the Royal Southern Brotherhood, a supergroup consisting of Cyril Neville, Mike Zito and Devon Allman, son of Gregg. Benoit¿s roof-rattling swamp blues will likely be leaning on 2011¿s critically lauded album ¿Medicine,¿ on which the noted conservationist took aim at the BP oil spill. The Cajun rocker will play 9 p.m. Thursday and Friday with the Brotherhood at Bamboo Room (25 S J. St., Lake Worth). $38-$42. 561-585-2583 or Bamboorm.com.
