Well I'l chime in with this:
I grew up in Wester New York. I moved to Los Angeles in 2009 to advance my career. I tried NYC first as it was much closer and I could still visit family for holiday, however the environment wasn't as accommodating to working musicians. My drums stayed stacked up in my closet and every venue and studio had backing. I had to bring my breakables all over town, and taking a cymbal bag/pedals/snare/sticks in and out of cabs, subways and up and down flights of stairs in old buildings wasn't awesome.
Los Angeles provided more of the style of music that I was after, straight ahead rock, nothing fancy, as well as a much easier time with gear transportation. I've been here now for 14 years, so I think I made the right move. However post-pandemic a lot has changed. Many many musicians left in 2020 for places like Nashville, Austin, and Vegas. Cost of living and local politics have played a huge factor in the mass exodus.
California actually outlawed musicians from working as independent contractors in January 2020. This was a huge blow to people like myself and caused many of us to lose gigs even before the world shut down. The law has since been walked back some, but still.
I have been entertaining the idea of making another huge move, this time to Nashville. I've been there the last couple years, and have had no trouble making connections and even landing some session work while there. It's very welcoming to live musicians in particular. The studio scene isn't just a bunch of "producers" who are programing every instrument and having some singer just karaoke over it like they do in LA. Every venue is filled with bands playing all day and all night, not DJ's who are just using a laptop.
It's a hot topic in my house right now, and it seems like it could happen in the next couple years if not sooner.
Don't get me wrong, I love LA, and I really want it to work here, but it's getting harder and harder to justify why I stay. Most of the gigs I have are with bands that have members scattered in other areas anyway, and no matter what someone's gotta jump on a plane to kick off the tour. I do a large amount of Recording Session work, however it's all remote. I haven't stepped into a "real" studio in over 2 years, yet I'm tracking constantly. So that can be relocated to anyplace with ease. And as for my teaching practice, that I would have to start all over, I don't like it, but I have done it before when I moved to LA, and it's also the smallest portion of my income.
