MUSIC: It’s almost Christmas and what better way to ring in the holidays than by supporting your local music scene with a Punk Rock Christmas show?

Pink Elephant is loud and aggressive and blows you away with its twin-guitar assault. Instrumental surf rockers RoarShark takes you to the beach just don’t expect them to sing, while stuck-in-detention garage band Bad Kids adds extra snarl to this show. It’s A Punk Rock Christmas takes place tonight, 8 p.m. at Tala Vera, 155 State St. $5. tala-vera.com.
