Phil Lesh and Friends will be spicing things up for their upcoming fall tour. The news was revealed via a post on the Grateful Dead Facebook page, which reads:

Phil Lesh & Friends’ 2013 Fall Tour will be integrating exciting thematic elements into each performance. To keep everything a surprise, we don’t want to reveal too much… it could be an album, a band, or some special unique thread that PLF will weave into the tapestry of each set. The journey continues… See you there!

These kinds of thematic shows are not completely unusual for Lesh. The bassist has been known to create themes for his setlists, and he played Workingman’s Dead in its entirety with Furthur at this summer’s inaugural Lockn’ Festival.

As previously reported, Phil Lesh and Friends will be kicking off their fall tour with a four-night run at the Capitol Theatre in Port Chester, NY October 31-November 3. The band will then play five nights at the Best Buy Theatre November 5-9 before heading to the Tower Theater in Philadelphia November 11-13. For these shows, Lesh’s band will include his son Grahame Lesh, guitarist Anders Osborne, North Mississippi Allstars guitarist Luther Dickinson, keyboardist/fiddler Jason Crosby and drummer Tony Leone. American Jubilee will be opening each night.
