Beth is a legal resident of Frankenmuth, Michigan (and technically *does* have a small place there) but typically drives around the state in a secondhand Airstream Interstate 24X the painted the off-maroon of an old scab, which really was not worth the price. This inadvisable purchase was mostly to feel like a real rock star, but life on the road suits her just fine, with no attachments to tie her down. Usually she's in and out of Detroit, since it serves as host to about half of the gigs she gets offered. Sometimes, she claims either to be from or to live in Gaylord, Michigan, but this isn't true - she just thinks it's funny.
Beth mostly gets money from gigging, in as much as she's able to out in the middle of nowhere. She has, in the past, also given novice-level guitar lessons, but they're few and far between because no responsible parent would ever allow this woman to teach their kids anything. Most of the money goes towards keeping her tour bus in barely-working condition, so that she can shower, eat, get around, and not freeze to death during the night. The rest of it mostly goes towards indulgences, like alcohol and other substances, or "absolutely essential" music gear she has used maybe twice ever.
Performing at the five biggest live music venues in the world is kind of Beth's way of making more tangible, actionable, achievable version of "get famous" - if she can play all five, she knows she's made it, her music has had an impact. Then she can just enjoy the money and influence and comfort of a purely hedonic, rockstar lifestyle.
As for how far she'd go? Enough to risk her life, certainly, though it's unclear exactly how aware she is of her own mortality, vs just thinking of death as something that happens to other people. Killing people? A solid maybe. She's not gonna become a hitwoman or something; at worst, she could probably convince herself that killing someone to protect her career was an abstract form of self-defense, but she's really too passive to go out of her way to murder someone - plus she knows she doesn't really have the powerset or knowledge to cover it up.
Beth was 14, still living at home, and idly listening to music while pretending to study.
Try as she might, she was never able to find the song again. If pressed, she'd describe it as a "maybe it isn't normal teenage angst to be feeling this way type beat", and for the first time in her life, she felt like somebody else got it. The full shape of the beast, the scale and the insurmountable horror of the world as it exists now. Beth was already familiar with the idea of cosmic horror, but it had never really registered as anything more than a flight of fancy. The idea that a full and total comprehension of Biology or Astronomy could drive a person to soul-shattering despair, a maddening, smothering blanket of futility at one's own insignificance in a greater whole, never really rung true to her.
Economics on the other hand?
Well, at least Physics has rules.
And for once, there was someone else who could see this terrible thing, this great machine of churning smoke and bloodied gears, devouring everyone it saw as it tore across the ravaged landscape. She had never been more elated to be told that it was okay to be angry.
