There’s a very ravey pre-Christmas party going down at First Avenue. We’re of course talking about Get Together, the semi-regular DJ night that began in 2013. Headlining this iteration is DJ Frankie Bones, who helped familiarize New York City with rave culture in the ’80s and ’90s. The underground trailblazer championed the PLUR (peace, love, unity, and respect) philosophy, which encourages clubbing communities to aspire to higher ideals. Get Together 7 will feature a special birthday set from Woody McBride (aka DJ ESP), the pioneering Midwest DJ who was the subject of a City Pages cover story in August. Also performing are DJs Fresko, Amy Pickett, Casey Borchert, and Cloudy Kid. Host Bobby Kahn will present his So You Think You Kahn Dance Dance? class.
