Released in 1973, Lou Reed’s ‘Berlin’ album was everything listeners weren’t expecting after its career-defining glamrock opera predecessor ‘Transformer.’

Berlin moved Lou from the streets of New York into the personal hell of a fictitious couple, in a concept album which tracks their toxic relationship from its beginnings to its tragic end.

Equal parts harrowing, somber and beautiful, it’s difficult not to be affected and even disturbed by what is probably Lou’s most interesting album.
