The Gromble 

An awesome rock band based in southern Orange County.

"Laguna Niguel quintet, The Gromble, sounds exactly like what you would imagine a band to sound like with a name based off a 1990s Nickelodeon cartoon. Like a food fight at summer camp or a make-out session on the playground, The Gromble evoke feelings of those wild, fleeting moments of rebellious freedom while adulthood loomed in the shadows."

-KROQ
