I really tremendously enjoyed watching this!

It is hard to know how much or whether I should recommend it because if you are not a fan of the album, it would probably be pretty boring!
I will say I realized it was going to be a great time within the first 5 minutes, so if you are not hooked, you might not commit to the full ~80? minutes. Naturally, much of the documentary had the music from "So" playing.
A little trivia - Gabriel definitely has a streak of OCD and spent one year of his life devoted to making this album at a country farm house/cow barn he rented and equipped for the purpose. The shadow voice he uses for Mercy Street was recorded early after he slept in the studio before he was up long enough to lose his "morning voice" (the shadow voice vocal is an octave below his normal voice vocal). In "Don't Give Up", the drums are mixed in at 10% below recorded speed which gives them a unique character, and Tony Levin used a diaper under his strings (bass) to dampen them! I don't think I'm spoiling anything by mentioning these. Hell, I enjoyed the heck out of watching the guy playing with the mixing board on the various tracks from "So" as he was talking about it!
PS- Prime is offering this as one of a series of documentaries on the making of several important albums (all free with Prime),so you might see what else is available! The series is called "Classic Albums" and here is a link to a list (currently 201 search results)!
