Although he wrote a song insisting he was just an Average Guy - "Average in everything I do/ My temperature is 98.2" - Reed was anything but, and that's made clear in this excellent, well-researched biography.
Brilliant, sensitive, cruel, cantankerous, controlling - Reed was the definition of the Difficult Rock Star.
DeCurtis first met his subject in an airport in 1995. Reed recognised him as a Rolling Stone writer who had reviewed his album New York six years' earlier .
Reed asked - "How many stars did you give it?". "Four." "Shoulda been five," said Reed.
DeCurtis doesn't make too much of his personal connection to Reed but he's gained access to many of Reed's key collaborators - getting interviews from Bowie before he died, Reed's first two wives and fellow journalists and record company staffers who had the misfortune to be assigned to Reed.
One, Jeff Gold, describes dealing with Reed as a "Me burger with I sauce" experience.
"It was all about Lou. Lou did what Lou wanted to do on Lou's timetable."
While DeCurtis does a creditable job with the Velvet Underground material the book really comes alive when detailing Reed's solo career; his descent into speed addiction and his life in the erotic underworld of 70s New York.
