I think it's an amazing thing to take something old and give it a new life or a new twist. Not replacing it of course - but building on it and evolving it. I have not done much of this but a very long time ago I played the church organ and in recent years sometimes I make piano improvisations based on the chords from chants written for psalms.
Yes I'm going to Hive Fest - I wish you could be there too but understand it's impractical/expensive for a lot of people, especially this year,
