Yes, it was hard mastering work but I think it was worth it. These gems from the groundbreaking female Singer/Songwriter are going to make a wonderful Gold CD from Audio Fidelity. Nice warm sound, the harshness of previous versions gone. Slight tape overload in certain songs and tape creases, etc. revealed, no "fix it in digital" here. Pure sound from the analog tape to the HDCD/CD master. First album in stereo from Columbia tapes, no Verve mixes exist, sorry. So, to recap, we didn't use the Sony digital "Hits" mastering, we went back to the original analog tapes and recompiled, the way a good "Greatest Hits" album should be done. Hope you dig it. It's not going to win any prize for sonics but as I said in a previous thread, Laura Nyro is a Goddess..
