Mark Deming at AllMusic: Transformer and "Walk on the Wild Side" were both major hits in 1972, to the surprise of both Lou Reed and the music industry, and with Reed suddenly a hot commodity, he used his newly won clout to make the most ambitious album of his career, Berlin. Berlin was the musical equivalent of a drug-addled kid set loose in a candy store; the album's songs, which form a loose story line about a doomed romance between two chemically fueled bohemians, were fleshed out with a huge, boomy production (Bob Ezrin at his most grandiose) and arrangements overloaded with guitars, keyboards, horns, strings, and any other kitchen sink that was handy (the session band included Jack Bruce, Steve Winwood, Aynsley Dunbar, and Tony Levin). And while Reed had often been accused of focusing on the dark side of life, he and Ezrin approached Berlin as their opportunity to make The Most Depressing Album of All Time, and they hardly missed a trick. This all seemed a bit much for an artist who made such superb use of the two-guitars/bass/drums lineup with the Velvet Underground, especially since Reed doesn't even play electric guitar on the album; the sheer size of Berlin ultimately overpowers both Reed and his material. But if Berlin is largely a failure of ambition, that sets it apart from the vast majority of Reed's lesser works; Lou's vocals are both precise and impassioned, and though a few of the songs are little more than sketches, the best -- "How Do You Think It Feels," "Oh, Jim," "The Kids," and "Sad Song" -- are powerful, bitter stuff. It's hard not to be impressed by Berlin, given the sheer scope of the project, but while it earns an A for effort, the actual execution merits more of a B-.

Wiki: Berlin is the third solo studio album by American musician Lou Reed, released in July 1973 by RCA Records. A concept album, Berlin tells the story of a couple's struggle with drug addiction and abuse. Initially, critical reception was mixed but appraisals of the album have warmed over the years: in 1973 Rolling Stone declared the album "a disaster" but by 2012, the album was ranked No. 344 on their list of the 500 greatest albums of all time.

The concept was created when producer Bob Ezrin mentioned to Lou Reed that although the stories told by Reed's songs had great beginnings, they never really had an ending. Specifically, Ezrin wanted to know what happened to the couple from "Berlin" – a song from Reed's first solo album. Reed more
