Today, Bobby Weir took to Instagram to share a pair of photos of him and Tyler Childers rehearsing. The pictures come just a day before he is set to celebrate the 50th anniversary of his album Ace at Radio City Music Hall in New York on April 2 and 3.

Weir will be joined by the Wolfpack and special guests for the performances and though the guests have not been announced for the shows the photos show great promise for star-studded evenings.

Ace was released on May 1, 1972, and features a number of Grateful Dead adopted classics, such as “Playing in the Band,” “Black-Throated Wind” and “One More Saturday Night.” The double-feature will mark a special occasion for Dead fans to relive the magic of 1972 and celebrate the longevity of the Grateful Dead.

Additionally, the 50th-anniversary celebrations will be livestreams on FANS Live. Sign up to watch the shows here.
