Thanks Chris for bringing the thread back!
Let's see if I can add some that are missing. I'll start with Lee and search for the others lateron. Or anyone else can do it if they feel for it ;-)
Just search the bandcamp site for anything that's been added to Bandcamp since roughly December 2022 and/or anything that's not yet listed above and still worth mentioning, especially what's been released on a non-SY related label.
