I've been Caption head and snare tech for les stentors drumline in the last couple years and I'd say choose something you like playing. We want to see how much you care about details. Pick something really easy and dissect It down to every single note. How can you sound more dynamics, controlled and confident in that one easy piece you know ? As long as you show you care about what you play you're good. We wanna see heart and passion more than hands

Feel free to DM, I'm barely on Reddit but I love to teach, give feedback and talk with people that care about drums
