Karl - Kind of Blue was released in 1959, so wasn't covered in the books that I bought. According to the RIAA site it wasn't certified Gold (500,000) until 1993, which is hard to believe - its probably just when the record company paid to have it certified, which is not an automatic process. It went Platinum (1,000,000) in 1997, double platinum in 1999, triple in 2002. Miles only other big selling albums were Bitch's Brew (Gold '76; Platinum 2003) and Sketches of Spain (Gold '93)
