@thomas Most interesting. I felt really out in the woods most of the time, and was least confident with the songs I appear to have performed best at. And I'm sitting in front of OK-ish studio monitors here. 😄 It also taught me that being honed on a genre doesn't help as much as I thought.
What I was really looking for were the dead giveaways of former times where you could always tell by the cymbals. That is obviously gone, and impossible for songs that don't have a lot of them (e.g. 2nd one).
