Dec. 31 Secret Weapon New Year’s Bash Waiting Room, 6212 Maple St. 9 p.m., $10, onepercentproductions.com The only thing better than New Year’s Eve is New Year’s Eve on a Friday night. Celebrate this double dose of bacchanalia with ’80s cover band Secret Weapon. Priding itself on performing rock concerts rather than background noise, Secret Weapon transports audiences to the dawn of the MTV Generation. Hard Rock? Covered. Glam Rock? You bet. Children and fans of the decade will pump fists to Billy Idol and scream along to Bon Jovi. You didn’t have to live through the ’80s to enjoy this show. Whitewash jeans and Aqua-Net optional.
