I've been in ATX for nearly 20 years & started coming here to play since the mid-90s. Yes, it's terrible (pay, # of clubs, predatory 'booking agents' and club owners, etc), and yes, there are fewer & fewer clubs/bars to play at - for original and cover/tribute acts. Myself & many of the musicians I know do original bands, a cover or tribute act, acoustic shows, and still need to supplement with teaching or a day gig. It ain't easy. I'm grateful that every gig I regularly pull in 3-4x what has been described above. But, I'm also playing what folks want to pay for most of the time (covers)...my original band pays nothing after expenses.
How this is NOT the fault of a city management style that prioritized high rise commercial buildings, tech bros and their greed and a desire for government AND the citizenry to 'homogenize' into the cookie cutter 'WalMart/Starbuck/McDs/' mold found in every city/town along any major highway in the US...but sure, it's the broke musicians, of course. "I wanna live in the LIVE MUSIC CAPITAL OF THE WORLD...but no 'noise' after 9pm!"
That said, some of those same broke musicians ARE to blame, as well. Sometimes for the things mentioned by some here. Austin built its reputation on 'outsiders' and 'weirdos' and then decided to back corporate interests. Those corporate interests buy up all the properties, shut them down and that's the fault of the musicians? Yes, sometimes it is (in part). But a big part of the blame is on the city & the businesses & the citizenry.
