You see more arrangers in one block in Mexico than in an entire city in the U.S., as a rule.
I know of only one other guy playing one in the Shreveport metro area. A few years ago there were several, but most have died! One exception I almost forgot. One of the Mexican restaurants uses guys from Mexico quite a bit. They all play arrangers, most of them quite old, such as early Korgs, and PSR 2000s, etc. They usually are just here for a short while and then disappear. Maybe they go back to Mexico? Every one I've seen there has been really good.
There is just nobody promoting them or demonstrating them. I get a lot of people, many of them musicians, who are interested in what I'm doing, but even when I explain it they don't really comprehend. It's very common for someone to ask if I do my own tracks!
