Tracks 7, 9, 10, 12 and 14 are available on CD only. All tracks have been digitally remastered. A section detailing the noise reduction process from the booklet is given below:

"This reissue has been prepared by transferring the best available source material to digital tape, which has then been reprocessed by Sonic Solutions, using their unique computer NoNOISE systems. NoNOISE is designed to remove virtually all imperfections and aural distractions (surface noise, pops and clicks, scratches, rumble, etc.) commonly associated with vintage material, without substantially altering the basic recorded sound."
