Even beyond that, there are many musicians that I do not know personally or, some that I'm either loosely aquatinted with or just met that are easily contactable through FB. If i need a keyboardist for a last min gig, i can probably contact some1 i've never played with before but know through that platform. Additionally I can put a post out there to my community and get referrals etc. Eventually I do think Steemit will encompass these things.
