Michael Kang will sit in with Particle throughout the groups 8th anniversary performances at Boulder, COs Fox Theatre (10/9) and Denvers Cervantes Ballroom (10/10). Former New Grooves The Breakfast and U-Melt will open for the group in Boulder, while occasional Particle guitarist Brian Jordan will supply support duties in Denver with his own trio. Particles anniversary shows have drawn in an eclectic mix of musicians over the years, from gospel singers to colorful dancers to Doors guitarist Robby Krieger.

Particle played its first gig on a boat circling San Francisco on October 7, 2000. As of late, keyboardist Steve Molitz has devoted most of his time to Phil Lesh & Friends.
