STS9 has confirmed a series of official after parties for its New Year’s shows at Denver’s Fillmore. All three after shows will take place at the Casselman’s, a venue located in striking distance of The Fillmore.

The official December 29 show will feature Sexytime (a collaboration between crunkstep phenomenon Mimosa and ex-Boulder resident turned Bay Area beat machine Sleepyhead), the live debut of the enigmatic Paper Diamond, Lazer Sword, DJ Rootz, Archnemesis featuring Curt from Telepath and Lorn. The group’s official December 30 party boasts Bonobo (DJ Set), Up Until Now feat David Murphy of STS9, Two Fresh, Random Rab featuring Android Jones, The Great Mundane and Frequent C. Finally, the ensemble’s December 31 after party will bring together Tipper, Nosaj Thing (Visual Show), Teebs and Tokimonsta.

All three nights will also feature special live art and light show components. Robert Venosa, Martina Hoffman, Damon Soule, Android Jones and J Garcia are among the artists that will take part in the shows. Flower guru Anthony Ward—who was recently invited to do his 12th altar for the Dalai Lama—will also create a floral installation that grows over the course of all 3 nights.
