Tmay, that's a great purchase! Here's my take on your questions:
1 - I haven't noticed the stereo dropout myself, but especially on CD3 it wouldn't surprise me as it's a series of demos and will be of lesser sound quality.
2 - Well, it's not quite the entire Celeste output. But this box is really a Ciro Perrino box. The first CD, Il Sistema, is the first important band he was with. The next two CDs are Celeste proper. The first is the album as it was released in 1974. The second (CD3) is the English version of the album and some demos and outtakes from later sessions. Finally, CD4 is another Perrino project (along with Celeste bassist Battaglia), St. Tropez, not really Celeste anymore.
However, there are two other CDs released by Celeste not included in the box. The second album, was recorded in 1977 and was released with some demos on Mellow as "Second Plus." There is some overlap on "Second Plus" and CD3 with some of the demos included there.
There is also a soundtrack released by Celeste, entitled "I suoni di una sfera." I don't have that one and can't comment about it.
Perrino was involved in two other projects, one called Compagnia Digitale and the other SNC. SNC is sort of spacey, not as good but similar in spirit to St. Tropez. I don't know much about the other project. He also has some solo albums out.
3 - The titles of CD2 and CD3 are the same, reflecting that CD3 contains the English recorded version of the album.
Enjoy!
