Big Mama Thornton: Ball and Chain https://www.youtube.com/watch?v=vypSOetzlQo
a real blues classic. she lived it. she wrote it. she sang it.
these shots have little to do with the song other than the fact that there's a ball and chain. while the reference in the song is more about a drag in a relationship, this ball and chain fencing in Budapest, Hungary is closer to the original context of a prisoner being shackled with a ball and chain as a form of curtailing freedom. in this case it refers to the country's sentiments under Soviet control.
but let all that be for a moment and check out the shadows
