I just watched Grey Gardens again and it’s as bizarre and confusing as ever. A mother and daughter battle madness and bicker in their crumbling mansion whilst the Maysles brothers document their fall from grace in American society. It made me think of the decrepitude of some of Detroit’s finest buildings, which have been recently documented by Yves Marchand and Romain Meffre. I saw them on the Guardian website the other day. Such a shame.
