Rock Bars in El Centro CA?

Moveing to EL Centro CA some time soon. I'm turning 18 soon and plan to become a bartender at some point. I know I cant tend till I'm 20-21, but I was wondering. If there are any rock clubs around. Like, any bar or club that plays rock music, or metal music. I cant stand rap so I wanna find some place where there is good music playing if I wanna work around there. I could ask some friends I know there but I dont ge tto talk to them much. Thanks ^)^
