The Observer newspaper got musicians to choose their favourite films about music.
Song of Summer (a tv programme not a film, but as it's Ken we can let it pass. It was chosen by Neil Tennant of The Pet Shop Boys. He describes it as “an elegiac film about the painful process of creating music and the end of a creative life. It’s very emotional, unsettling and moving. Delius is an incredibly tragic figure, both fragile and brutal. Russell was brilliant at creating images to accompany music.â€
The list is mainly pop/rock music plus the odd county/ blues/ classical films included. There are films based on people (The Doors by Oliver Stone, Out of Control (on Joy Division), Walk the Line (Jonny Cash), Bird (Charlie Parker), The Young Ones (Cliff Richard). Documentaries included Amy (Amy Whitehouse), Cracked Actor (Bowie), 30th Century Man (Scott Walker), C*cksucker Blues (with a title like that it has to be The Rolling Stones), Woodstock, The Kids are Alright (The Who), Live at Pompei (Pink Floyd).. Others include Cabaret and the magnificent This is Spinal Tap.
