On May 25, Red Rocks Amphitheatre in Morrison, Colorado will host a screening of the Grateful Dead documentary Long Strange Trip. The screening comes in advance of the Amir Bar-Lev-directed film coming to Amazon Prime Video on June 2.

The Grateful Dead played 20 concerts at Red Rocks between 1978 and 1987. While VIP tickets for the screening are available now, GA tickets go up for sale on Friday, April 21 here. The screening is part of the Denver Film Society’s Film On The Rocks series.

Long Strange Trip features interviews with band members and other luminaries of the Grateful Dead world along with rare studio and live footage. Bar-Lev’s documentary spans nearly four hours and tells the story of the band in an emotional and endearing fashion without pulling punches.

Executive producers include Martin Scorsese, Emma Tillinger Koskoff, Rick Yorn, Thomas J. Mangan IV, Alicia Sams, Andy Heller, Sandy Heller and surviving Grateful Dead members Mickey Hart, Bill Kreutzmann, Phil Lesh and Bob Weir.
