Fuck it I've made a pretty big list of Pow Wow drum groups either for ppl already in the pow wow scene but wanted more drum group recs, or for people just getting into pow wow music & wanted some recs. I've split them up into groups by where they were founded and (usually) most of their members are from, because if you go to a pow wow in one of those countries, then you're a bit more likely to see the groups that are from there in person. Note that this is not an exhaustive list, there's a LOT more that I'm either forgetting, haven't heard of, or they have not posted their music on any streaming sites.
