This album is not available on CD, and is very hard to find on tape and vinyl. The manufacturer has not released it on CD (as far as I know).
Bought the tape (the only copy available) new from Amazon last year. Fortunately, my tape deck took care of the noise with Dolby C Noise Reduction setting and burned to a CD-R.
This artist sounds very much like Madonna, even so Deniece Williams (I once mistook her as Madonna for "Without You," an excellent song).
If you like Madonna, Deniece Williams, and other artists with such an amazing, renowned voice, One to One's Forward Your Emotions is a great choice. That is, if you can find one.
One 2 One's Imagine It (notice they changed their name) and One 2 Many's Mirror are available on CD, and I guess not nearly as rare. Still, One 2 One's Imagine It was not a great album from the early 1990s, but One 2 Many's Mirror is excellent but sounds dissimilar from Madonna.
Wonder if these artists knew each other or borrowed ideas for their names, I have not a clue.
I have all three albums, although I'd rate One 2 Many's Mirror four stars (one more star than this One to One's review for best quality sound possible - on CD). Hope this helps, if you like quality, obscure music from the 80s.
Wish I had 1-2-3 album too. It's probably One to One's rarest, and I could not find it anywhere. (Maybe someday I will luck out - I once heard a song from 1-2-3, don't remember what it was, and it was a very good tune.)
