What was the best music documentary you saw in 2021?

2021 may have been the Year of the ‘Rockumentary’ – with a number of high-profile music docs released over the last 12 months.
The biggest, of course, would be Peter Jackson’s eight-hour Beatles documentary Get Back, which follows the Fab Four during the recording sessions for their final album and concert.
It was also the Year of Britney, with a whopping *four* full-length Britney Spears documentaries released in 2021, covering the singer’s controversial career and battle for her financial independence.
Other great rock docs released this year include Woodstock 99: Peace, Love, and Rage, the Alanis Morissette documentary Jagged, and documentaries about The Velvet Underground and Rick James
