"While visiting my ailing grandfather during a cross-country trip last month, I ran across a cheap, unlabeled cassette tape in one of their closets. He and I popped it into a player and were amazed to find that it was a 21-year-old recording of him playing piano in the family living room. He wasn't aware that he had any recordings of him performing any of his once-formidable Chopin repertoire. He and I enjoyed listening to the warbly, old cassette, and his Chopin phrasings and interpretations brought back a wave of fond memories. He had forgotten that he could play so well. The cassette itself, though, was a tenuous link to the past: It was recorded impromptu in the family living room without any fancy equipment. There was little treble presence to the recording. At many points, the tape levels were maxed out, creating a distorted buzz. And of course, there was all the noise that one would expect from a 99-cent cassette from two decades ago. I was extremely pleased when I received your restoration CD, and can tell that you took more than $10-worth of care in restoring the old tape. The noise and distortion are greatly reduced, and the music shines through. What was once an interesting piece of family audio history is now an eminently listenable piano performance. Being a bit of an audiophile and tweaker myself, I played around with your digital transfer/restoration using some top-line audio software, to see if I could bring out a bit more detail on some of the more challenging tracks. In every case, after trying many different modifications, I ended up reverting to your version, which was superior. Many thanks for your excellent services, which I will be using again!"
