After a brief and unsuccessful stint as a Geffen Records artist, Hilton Head native Trevor Hall has released an appealing, self-titled CD on Vanguard. His music is a sort of spiritually-energized reggae rock, not unlike that of Savannah's own Passafire, or Michael Franti & Spearhead - like Franti's best stuff, it'll get you dancing, singing along, and thinking about the world in which we live. "Unity," the Trevor Hall album's standout track, was co-composed with the rockin' rabbi Matisyahu - who duets on the high-energy song - as a reaction to the terrorist attacks in Mumbai. Listen & learn: At 9 p.m. Friday, Nov. 13, Live Wire Music Hall, 307 W. River St. $10.
