Pro trumpet player here. He’s not only making up stuff off the top of his head, but he’s playing perfectly into the style and is using a lot of extended technique. If you don’t like the sound? Why don’t you teach him. I think he sounds fire and I wish I could be able to switch in an out of techniques like he does.
It's like if you put enough monkeys in front of typewriters and they just hit keys at random, eventually they will come up with a Shakespeare play. Same thing with this guy --- eventually he'll play el manicero...😅
Nice that he is providing some atmosphere and entertainment for his money! Better than the strung out useless drug addicts begging for money at intersections in the US!
