I understand, but the thing is,
you still don't need "drums". Percussion instruments are often improvised.
Years ago, I did a martial artist PC who was a percussionist. He had 2 escrima clubs that he dual-wielded. The clubs were essentially 2-3' long like the normal ones, but instead of being smooth, they were textured with ridges.

Struck together, you get a sharp percussion sound like when you do likewise with drumsticks. Rubbed together, you get a sound like a guiro.
I've seen Joe Bonamassa's percussionist use a rattle made from a 2-liter soda bottle with pebbles in it. There's no reason why you couldn't do likewise with a canteen.
