A while back, the late, great Jerry Garcia spoke about his time in the Grateful Dead: “A large part of my life, I’ve spent doing something, which has turned out being more fun than I thought it was going to be, and it’s lasted way longer than I imagined it might, and it’s taken me places that I would never, ever imagined. It’s hard to separate myself from the experience. After all, it is my life. For me, it’s 24 years of all kinds of stuff like everybody goes through — y’know, life and death, and kids grown’ up. And, y’know, the Grateful Dead has been this one, constant, continuous source during the whole thing.”

On the upcoming collection, fans will get a healthy dose of beloved Dead keyboardist Brent Mydland, who died of an accidental overdose on July 26th, 1990. Drummer Mickey Hart remembers Mydland’s time with the band with mixed emotions: “Brent was a beautifully charming, bright-eyed and bushy-tailed kind of a guy and crazy as a loon, y’know? He just went off the road, y’know? He just couldn’t take the Grateful Dead. The Grateful Dead killed him, like it killed almost all of our keyboard players. You wouldn’t wanna be a keyboard player in this band. It’s almost like a. . . It seems to be almost prophetic.”
