I think they are looking for 2 things:
1. unique spaces (concerts on a boat, private rooftop, mongolian yurt have a great appeal)
2. cheap-ish to produce music so it's profitable even with a small audience. Minimal band members, accoustic, minimal props.
So a cool dude with an artsy loft, an acoustic guitar and a unique musical style can probably do pretty well from what I can gather.
A quick calculus of 10 people at 20$ (or 20 at 10$, whatever), 20% Airbnb fee: as an artist you just made 160$ for an hour of music. You can actually earn a LOT more, the question is wether the demand is there. The struggle is to actually set up that cool space, and get popular enough to get reliable bookings.
Basically, I feel it's worth trying out at the launch since we do have a lot of musician friends. Worst case, we just pimp out our basement as a cool party venue and come out even ?
