I tried to send Guy a question/suggestion on his forum and couldn't. Seeing as the days of touring are over and probably any concert is far from happening at the moment (hopefully that will change), I was going to suggest the idea of working on some official live material:
1. On video, some DVD or Blu-Ray of the concerts that have been recorded in good quality.
2. If not that, it can also be a release in physical formats (Vinyl or CD) of a particularly good concert from a tour (the latter has the best sound technology), using the soundboard recordings and remixing them to have a sound optimum. Just ideas.
