Filmed on the closing night of this years Montreux Festival on July 16, this concert features Deep Purple playing their classic hits with the accompaniment of a full symphony orchestra conducted by Stephen BK Bentley-Klein. The orchestral arrangements give an added depth and range to the familiar songs and the band, who are clearly enjoying the experience, deliver one of their finest performances. With a career stretching back into the late sixties and global album sales in excess of 100 million, Deep Purple need no introduction.
