I've recently found a list of musicians who were recommended to be followed. I watched their insta profiles for almost 2 weeks and can recommend now some of them. You can start with James Blake and AlXXA. Their profiles are pretty cool and you can read some interesting info about their life and music productions. I can also mention Oliver Riot and Khalid. Maybe their genres of music aren't the most interesting, but the way how they control and pr their insta is interesting and may be helpful to some newbies.

P.S. The info about them I got at:
