First, I found this google doc: https://docs.google.com/spreadsheets/d/15wtaOQx91bdnDtAj7JVlB39z3r7T-eQb8S8cpQrUwp0/edit#gid=0
Which is a list of literally several hundreds of black producers and labels with music available on bandcamp. It was started by zach fruit (@/zacharyfruit) on twitter: https://twitter.com/zacharyfruit/status/1268166446133252097
If you're into punk, I also found this tweet: https://twitter.com/LaurakBuzz/status/1267842884566429699?s=19
It links to an article who lists several black punk (several subgenres) bands: https://www.okayafrica.com/black-punk-bands-need-listen-to/?rebelltitem=1#rebelltitem1
Most of which have a bandcamp
The official Bandcamp twitter has also shared this tweet (https://twitter.com/Bandcamp/status/1268799943927619584) which links to this: https://daily.bandcamp.com/features/artists-and-labels-offering-donations-special-merch-and-more-on-friday-june-5
"A list of artists and labels with special releases, including many donating to organizations in support of racial justice and change"
You can also check out their twitter if you've got the time, as they retweeted a bunch of artists who said they'd be donating.
