In 2005 Particle spent some time on the road with Trey Anastasio and his band of the moment, 70 Volt Parade. While on tour the group also got to know Les Hall, who augmented Anastasio on both guitar and keyboards. Though Anastasio seems to have retconned 70 Volt Parade out of existence (and replaced most members of that project) Particle kept in touch with Hall and brought the multi-instrumentalist onstage Monday at Chattanooga, TNs Rhythm & Brews. Hall played keyboards on other Desert Cities and Key Loop, as well as other assorted jams, deep into the groups extended set. On Sunday Particle also invited out guitarist Seth Dave, who opened for the group on a number of occasions this fall, for Below Radar at Nashvilles Exit In.
