For 12 years, Richmond’s ska and punk community has marked the holiday season with Happy Skalidays, a celebration of local music and holiday charity. The party takes over two nights at Strange Matter — the first show filled with rock, punk and reggae performances by Among Criminals, East Coast Secondaries, Broadside and Murphy’s Kids (pictured), who will play again the second night along with performances from Capital 7, Tsunami Rising, Proverbial and Eastern Standard Time. Proceeds go toward Comfort Zone, an organization that manages bereavement camps for children who have experienced the death of a loved one. Happy Skalidays loudly rings in the season at Strange Matter on Dec. 16 and 17 at 5 p.m. Night 1: $5-$7. Night 2: $8-$10. 447-4763.
