This set is advertised as providing five classic original Elvis albums -- Elvis Presley, Elvis, Loving You, Elvis is Back, and GI Blues. But considering the large number of bonus tracks, it is really more like six albums' worth of material. Some of the albums are not Elvis's best work by a long stretch, like the GI Blues soundtrack, but I even enjoyed that quite a bit.
His debut album on RCA, "Elvis Presley", is one of the great classics of rock and roll, and the other albums here are generally not far behind. This is all pretty great stuff.
The bonus tracks are a mixed blessing, because I had been looking forward to the experience of listening to these albums as they were when originally released. But, you can get that experience easily by ripping the CDs and only listening to the original tracks, if you'd like.
The only drawback is the small print. I mean the print on the boxes is too small to read without reading glasses and a lot of light, if you're an old fart like me. That's the worst thing I can say about this set. Great stuff overall.
