I was excited to see this pop up in the "Latest Posts" only to find that the original post is ten years old and the link to the original article seems to be deceased! But, also, the landscape of remote recording work has dramatically changed over the years, and I think it's an excellent topic to revisit frequently.
I work frequently as a session musician and arranger in a remote capacity. A lot of it is through a specific web marketplace/platform – in my case, Soundbetter.com, and
here's my page for that.
But a lot of it also comes through friends and colleagues I've known over the years who need something I can do. Writing arrangements for various ensembles, recording saxophones/flutes or keyboards, things like that. Occasionally, writing and producing an entire track from start to finish, when the budget is there.
Even with the online marketplaces and whatnot, I've found that old-school rules of business apply, maybe counterintuitively, to remote music work. It's still all about who you know, who knows you, who trusts you, and who likes to work with you. They recommend you to others, you build a reputation, etc. The mediums of communication evolve but the foundational human principles seem quite resistant to change.
