Essential lesser known artists for someone who’s trying to cover as many as possible?

Hey guys, a while back I undertook the insane task of listening to, rating, and briefly reviewing as many vaporwave albums as possible. I’m currently nearing 5,000 albums completed with thousands to go! I’m planning to post my massive Excel spreadsheet somewhere once I finish for you all to see.

But I need more suggestions! What are some amazing and often overlooked artists?
