Long Strange Trip was originally a four-hour movie before Amazon cut it to a six-part TV show. Produced by Martin Scorcese, it tells the full story of the band The Grateful Dead. It’s an account so detailed that it will satisfy the biggest Deadheads, but it also can be appreciated by anyone. The focus is the band, but it’s also the band’s significant impact on Rock history, and by extension, on American culture. I didn’t know much about the band and I couldn’t stop watching.
