The biggest thing I'd do is stay away from any major artist as they are all focused on short burst of exposure. I've worked with some of biggest names in electronic music and use to run a massive blog in dubstep genre. Majority of labels, agents, and managers don't know marketing they rely on their network based on artist who are already successful. Secret sauce is always have all platforms and outlets push to the things you control, website. If you focus too much on one platform like Instagram, Tiktok, SoundCloud, etc. you can't get them back. Always point to the website where you make that the platform you market off of. Why use things like Bandcamp or anything else when you can have your own ecommerce shop setup to sell your own stuff. It's hilarious how far behind the music industry is in modern digital marketing. It's all vanity stuff and artist just fall off until next release if lucky.
