For years, Southern California has churned out first-rate reggae bands. Rebelution, which formed in the Santa Barbara are nearly 20 years ago, started out as a college party band but quickly became a national act after its first album, 2007's Courage to Grow, blew up thanks to singles such as the soulful, Sublime-like "Safe and Sound." The veteran band performs tonight at 6:30 at Jacobs Pavilion at Nautica. Iration and DJ Mackle open.
