4 NEW ELVIS MONO-TO-STEREO CDs!

New audio technology has made possible for the first time a HUGE improvement in the sound quality of Elvis's classic early tracks. Hear these songs as you've never heard them before -- in STEREO! Get all 100 tracks for a discount, in one convenient package! Originally recorded in the days of monaural (which is one channel, one dimensional sound), all of the music was squished together. Mono is NOT a natural sound. But thanks to recent advances in audio engineering, it is now possible to take mono original masters and convert them into stereo. Instruments and vocals are separated (like what happens at a modern. multi-track recording session) and then mixed to stereo for a more lifelike acoustic ambience. The improvement in sound quality is like the difference between an old black-and-white TV with rabbit ears, and a new 4K high-definition color TV set! ELVIS COMES ALIVE in these classic performances. You notice more details in the original music -- things you never heard before! As soon
