Other than the lost Byrd Gang songs, I think Max released everything he had done prior to jail. When he was with Amalgam, I spoke with the CEO, Next, and he told me that Max had a ton of songs that hadn't been released. He said the number of unreleased songs could make up a Library of a Legend 2. I believed him. Then he told everybody he was going to release 1 new Max B song for some movie he was making. That never happened.
Max now has a new record label, Phase One, and they bought all of Max's previous catalog. They even "bought" the LOAL and erased the "WAVEment and Masar Presents" part of the cover. At least they got it on streaming services for everybody to listen though.
Anyway, if Next couldn't even release 1 new Max B song, in like 5 years, when he is losing money off Max and would make more with unreleased songs, and Phase One has no unreleased Max songs (which they could also make money from), I have to wonder if there are really any unreleased Max tracks left. It's been like 8 or 9 years and we haven't gotten any new pre-jail Max B songs.
I know Jimmy has all of Max's unreleased Byrd Gang songs, but he redid them with a different artist (like Matrix). JImmy is holding on to Max's unreleased songs out of spite for Max dissing him and his girl. I don't think we'll ever be able to hear those old unreleased ByrdGang tracks.
