As previously reported, Particle and Lotus will share the stage at Denver’s Fillmore Auditorium on Saturday, October 17. Particle has now confirmed that Michael Kang will fill the rotating fourth member spot in the band that evening. The String Cheese Incident mandolin-wiz has collaborated with Particle numerous times over the years.

In related news, Particle’s Steve Molitz recently shared the stage with two former New Groove of the Month bands. This past Saturday Yamn and Roster McCabe performed together at Denver’s Owsley’s Golden Road. Molitz augmented Roster McCabe throughout its entire set, including Michael Jackson’s “Bad,” the theme from Ghostbusters and 2PAC’s “California Love.” In addition, Molitz stepped out a bit early to play on the final song of Yamn’s set, “Joey White.” Roster McCabe will perform at the Aggie Theatre in Fort Collins, CO this evening, while Yamn’s next performance will be at the Gothic Theatre on October 16.
