'Making a living from live music died a long slow death based upon two event time periods and is pretty much gone now:'
This is actually not true. It may be true for jazz (always was) but there are tons of musicians making money playing live. But if you're a jazz snob who won't lower himself to play a gig and put your heart into it, well, even that won't work. I've lived on music a few times during the last fifty years, but now that I'm retired from my day gig, music supplements my income. I play about 40-50 jobs a year, but there is a locally-based group that is a regional act, playing about 90 gigs a year, and several of them are full-time musicians. One of them also owns a music store and the rest have regular jobs, although I have no idea how they keep them. Everybody in my band, which is very similar to the regional act except we usually just play weekends, has a regular job except me. The band owner runs a multi-million $ contracting business. These two bands I'm talking about get $2K to $10K for a show. The other guys do more traveling than us, but it's all by road. I filled in for their sax player once and they had six gigs in eight days. My pay was about $1K. Both bands play what we call 'party music' here in the South - Motown, Beach, current stuff that we can use, etc., and a big PA, lights, outfits and just good old-fashioned crowd-pleasing favorites and a little show. We just started doing the Huey Lewis 'Heart of R&R', but the live version with the 'Tower of Power' horns. I play the tenor ride and the harmonica part plus the tenor horn part. We will use the charts on a new song for a few times, then it has to be memorized. We revisit long-time numbers about twice a year with the charts just to prevent 'parts-drift'. We even have a decent arrangement of 'In the Mood'. We have two saxes, a 'bone and a trumpet, so we can arrange anything and sell it, even big-band, to some extent. So, while it's not the house gig on 'Dancing With The Stars' (I have a lot of respect for those guys) it's not exactly a garage band either. And there's nothing to prevent any of us from taking a jazz gig now and then on the side, but there basically is no jazz culture here, even with several major colleges/universities in the area with vibrant jazz programs. Those guys that stay around here wind up playing in the kinds of bands I'm talking about and doing 'jazz' on the side for tips.
