I can appreciate pawciaob1's enthusiasm for wanting to find rare performances either via rehearsals, demos or concerts. We have all been excited and frustrated at one time or another following and supporting this band. I'm sure many veteran fans here have tried to contact the band or associates relative to what they may have and what the fans would like to be released. I also realize how unrealistic it is that the band would release any archival material that obscure. They haven't released anything since the remixed boxsets which was 2007-2009. Then Sum of the parts documentary and R-Kive in 2014 and the last Domino compilation in 2021. I was very disappointed and somewhat surprised that they didn't continue releasing something each year after 2009. The band surprisingly contracted with themusic.com and released every show of the 2007 tour. This certainly wasn't a big money maker, but it showed that the band may not be as precious about letting out performances that may not be up to standard. I'm not sure if there was a complete lack of interest on the band's part or something to do with their record contracts. The first talk of archival releases such as soundboard tapes was way back in 2001. That actually seemed like the band had some interest and were quite willing to get those tapes restored and released in some form. At the time, it was still common to release cd's and downloads were still a very new medium. It may have been too expensive for the very small amount of consumers for them to even bother.
Now in 2023, there are so many different mediums, and you find that many bands are releasing concerts via downloads and streaming services. Nugs Net is a very popular service which many bands have contracted to provide a platform for this type of product. There are many jam bands who by nature release all of their shows but there are also huge groups like Metallica who have used this service. They may actually be a good one to compare with Genesis in that they are/were very successful and by no means need the money. Youtube and other streaming platforms could be made available as a subscription service. I feel that unless a platform was created with the very objective of releasing archival content, such obscure things such as rehearsals or demos would have no chance of being released. Ok, maybe if the band does expanded boxsets of each album you may get a few tracks that they feel are of a certain quality or are very unique but they will not release 10 disc sets.
The band also hasn't really had an active website for many years which does show to some extent that they don't really want to interact with the fan communities in the same way they did back in old official website. Maybe that will change in the coming months or years, but who knows. It was really nice when the old site had access to people like Nick Davis and others associated with the management as it seemed that some suggestions were able to be made even if they weren't taken in serious consideration.
