Donald Fagen and Walter Becker are a rare breed of 70s music legend. They never traded on cool or looks, and they've got hits but could never be considered pop stars. The Dan are simply pure musicians, playing not because they need the cash but because they need to play. That's why these performances, revisiting 1977's Aja on the first night and 1976's The Royal Scam on the second, can't be considered a nostalgia trip. Fagen and Becker are jazz cats - don't think for a second we'll get straight-up faithful renditions. Steely Dan play Massey Hall November 25 and 26.
