1966
Several music reviewers give rather deep insight into the albums Niel made during these years.

I was interviewed at the insistence of the video crew in NYC.
I told them it was 30 years ago that I worked with Niel for 5 hrs. I had forgotten about the talk that day about Niel not wanting to sing. He sat and pouted as we setup. Out of earshot, I asked Steven Stills, "what's the matter with him". It turned out that it was the first time he had sung in the studio. Apparently they convinced him to do this in New York where all the LA producers, hangers on, and engineers were not around. I had been mixing some jazz in the mix room when the call came down from the offices where they had met with Ahmet Ertigen or Jerry Wexler. They did Mister Soul. It was fine... They took the 8 track tape and left. It was recorded on Ampex 8 track #2. (Number 1 was owned by Less paul).
I was uncomfortable about being on camera. I had no idea what kind of spin and content they were after. I had forgotten most of what I'm saying above. Watching the video I waited nervously to see what they could have salvaged from my disjointed interview. My name was listed on the online description, Bruce Tergesen. The reviewers who had followed Niel through the years gave amazingly insightful observations about the albums released during these years. Finally it reached the end and my interview was not included, whew! OK, just as well. If your a fan this DVD might demystify the wide variation in style and collaborations in these years.
