In honor of the Grateful Dead’s impending 50th anniversary in 2015, Phil Lesh’s Terrapin Crossroads will celebrate the landmark throughout the year. Lesh will host a pair of shows per month that reflect each year since the band was first formed in 1965. The first two shows will come on January 2 and 3 when Lesh welcomes Stu Allen, Scott Law, Jeff Chimenti and Cody Dickinson for a full set of music from the years 1965 and 1966, respectively. Due to the scarcity of set lists from ’65 and ’66, these shows will have normal Phil Lesh & Friends second sets.

In addition to the shows, the bassist will also host art exhibits, conversations with Phil about the shows and their context as well as memorabilia displays tied to the shows themselves. Tickets to the first two shows go on sale today at 11 AM at the Terrapin Crossroads box office and December 4 online.
