This already exists at thousands of local music venues around the world. It doesn't pay enough to live reasonably on, which is obvious if you just look at the numbers. Even with a megastar ticket price of $300*(50 attendees), a single show barely moves the needle on living expenses once split amongst a band. You need to do perform again and again, to the point where you can't charge $300/ticket. That's basically a residency, which is common in places like Vegas for artists at the end of their career. If you tour instead, your costs go up massively.
