Yeah. I mean, there's sadness, but what's interesting actually is when you put it all together, it's just life. There's a moment, you know, I did write a piece specifically for the project much later when it came time to record it. And the idea was, this is going to be the piece that's about my experience. And I really desperately wanted it to have this up and down, feel the journey, kind of Lord of the Rings landscape. At the same time, it's supposed to be a five-minute piece for solo cello. And I'm such a doofus, but I couldn't get that piece out. And I kept trying and failing. And so I started improvising every day to see what would happen and how I would get there. And it was really fun, but I wasn't making this epic that I had in mind. And it was the weekend before I was walking into the studio. I still didn't have that thing done or even really know what it was going to be. And so I finally just totally gave up. And I said, all right, whatever is coming out is the piece. And like it just kind of it just kind of showed itself immediately. And very quickly, those fun improv sessions evolved into one of the most unabashedly joyful compositions I've ever written. I couldn't force myself to write the piece that I wanted. But when I let go and just played, I came away with the piece that I needed. I gave it the same name I've given my project, Immunity.
