I've been trying some Joker impressions lately, but they're too much of a Mark Hamill Joker, too forced as well. When I recorded this one, I thought it was pretty good, not exactly what I want, but the voice is somewhat what I'm trying to create. I'll still be practicing a lot, since it's far from perfection.
The music playing in the background is the finale music of Batman Returns. There's a Killing Joke Joker impression on Youtube (This one: https://www.youtube.com/watch?v=NC16orUje4M), and I liked the music, it's also a reason why I liked this recording. The timing was pretty good for the first time. previously, I was too slow.
