The Big Melt is a documentary film about the Sheffield steel industry which combines archive footage with a live soundtrack. It was made by Jarvis Cocker and filmmaker Martin Wallace for the 20th annual Sheffield Doc/Fest in 2013, to celebrate the centenary of the steel industry. The film was made using footage from the BFI National Archive.
The first annual Sheffielf Doc/Fest was in 1999 
Its definitely incorrect because it says its 20th annual doc/fest was held 2013, so probably the first one was in 1993. Probably hard for the system to get because it doesn't say anything about the first one
