In film, you are a totally different person than in the video.
But I'd say recording and playing on stage are two completely different things. Being up there in front of all those people is like jumping off a cliff into icy water. The recording process is a totally different energy.
I will say that a lot of art, some of the best art, has very powerful and meaningful messages behind it, and the more you read the stuff on the walls, the more you learn the artist's intention, and you have a totally new point of view of what it's about.
I had a tryout when I was, like, 19 and totally not prepared. I was 170 pounds with homemade gear. At that point, I realized how far I had to go to even get looked at. Then, when I was 22 or 23, I was much more prepared, and that second tryout went way better.
I think that veganism is a totally great choice with incredible benefits, but I don't think it's reasonable to expect other people to be vegan or to expect everybody to be vegan. You can proselytize all you want, but being vegan is a pretty intense choice for a lot of people.
