This has received a Grammy nomination for Best Music Film, and I can see why. It's a good look at the creative process of the musicians at this point in their careers, experimenting for the first time since 1993 by performing to small audiences and then tweaking the albums (Uno, Dos, and Tre) according to their reaction. There is a good mix of interviews/studio time/live performances in the film.

Note: You can watch this on Qello.com with a free 7-day trial. Also for the record, I wouldn't consider myself a huge Green Day fan. I've always enjoyed Dookie and American Idiot, and I saw them at Lollapalooza in 2010, but otherwise find it difficult to listen to most Green Day albums from start to finish.

In the great "Heart Like a Hand Grenade," we see Green Day suffering from insecurity and doubt as they make the modern classic American Idiot. Ironically, in the mediocre "Cuatro!", we see Green Day with delusions of grandeur as they make their awkwardly indulgent garage-rock trilogy. I'll rarely complain much about getting a behind-the-scenes peek at one of my favorite bands, but this is even more scattershot & oddly dull than the trilogy whose formation it documents...& that's quite an achievement.
