Dec. 31 Happy GOO Year Slowdown, 729 N. 14th St. 9 p.m.-2 a.m., 21+, $15 ADV/$20 DOS, theslowdown.com For those of you brave enough to have attended a GOO New Year’s party, you know it’s kind of like an episode of “Survivor.” Only those who can survive the lines and massive crowd are worthy to reap the benefits of a party so epic that I’m surprised it isn’t sold out as I write this. For those not familiar, GOO was a monthly themed dance party started a few years ago by members of The Faint. Now more spaciously dated, GOO brings its annual NYE celebration to Slowdown, this year featuring guest DJ and Reader contributor Brent Crampton. Masquerade-themed, with a huge dance floor and a champagne toast at midnight, this event is at the top of many lists to ring in the new year.
