 Glenn Meadows remastered the CD set from the digital masters archived by Donald Fagen, Gary Katz and Roger Nichols in 1982.The digital tapes were prepared because the original analog tapes were in very poor shape.The earliest CD mastering for all the Steely Dan albums in 1985 used these digital tapes but MCA used deteriorating analog masters for all later CD pressings until the 1998 remasters.
