These songs are harrowing but beautiful and ultimately rewarding if you can survive its labyrinthine descent into heartbreak and despair. The most melodic songs include Caroline Says I and II, the wistful Oh, Jim, the painful The Kids, the bleak The Bed and the soulful Sad Song. Over these beautiful melodies Reed lays his vocals that are so genuine, so apt and so gripping that listening to them is like being privy to the private details of a doomed relationship. Of course, these all fit the complete picture to create one of the most cohesive and searng concept albums in rock, from the jazzy intro of Berlin with its lounge piano through the spoken poem of Lady Day, right to the melancholy last refrains of Sad Song. The grand production and sympathetic arrangements add gravitas to the somber mood to create a dark masterpiece of epic proportions. Somewhat inaccessible to some fans, Berlin has nevertheless improved with time and remains one of Lou Reed's greatest albums.
