I recently started utilizing the Entertainers plugin for the first time. One of the options is to play the drums, and I've read that you can use a maximum of 4 drums for the best performance. Finding drums has proven to be quite difficult. I know there are two at the House of Earthly Delights by the door, but they're both owned and I can't snatch them without getting a bounty, which I'd rather avoid. I also remember there's one in the Corprusarium. But there's also a lack of info online about where to find drums in general.

Anyone know where to get four drums?

I found one in the Corpusarium, it is unique though (Guar skin drum). You can still use it for the plug in I think.
