Gallery widget on each page/post based on that post/page's media uploads

Looking for a functional gallery sidebar widget that will show images from media uploads per post or page.

Here is what we are trying to do; we have client who has various “artists” pages (default page templates) and for each artist, we’d like to add a simple gallery in the sidebar.

To be clear, artist1 will have a sidebar gallery ONLY for artist1, artist2 only for artist2, and so on.

Does anyone know of or has seen a plugin that can do this?

I’ve found a few that can take images from a specific post / page or from direct uploads, but they are basically global and not based on per page/post.
