Let me say first, kudos for playing the Bolero excerpt end to end so many times in a row, with so few flaws. Really. That shows a lot, just being willing to do that, and then actually pulling it off with such great results. Great playing.
Not as a criticism, because any willingness to play for the peanut gallery here is courageous, but I'm not a big fan of signature mouthpieces. Yay, Alessi can play on a soup bowl, but I'm not Alessi, and I'm not any of these guys. I'm not sure just because some hero plays a mouthpiece I'd be likely to buy that mouthpiece. I might actually be lead away from it, because I know I'm not that kind of material. Anyway, it's still interesting to hear the comparison, and more interesting than anything was how well you held up through all those Boleros without breaks or edits.
Let me know what you think if you like - it was an interesting recording project and I've decided to lean into the vulnerability of it rather than away from it. It's always possible to put a lot of money and time into something to make it sound polished and "perfect" but this more raw and close look gives us more to think about and hopefully learn from, I believe
I can hear why you balked on putting the recording up. This one wasn't at the same level that your previous recording was. The easiest stuff can be the hardest. It seemed to show in your face that you weren't really happy with it as it was happening. I've done some recordings I've just deleted because I thought they were a bit embarrassing, but others maybe didn't hear all the mess I thought I created. You've established your skills with 8 Boleros in a row, I think a little junk between notes in long slide transitions can be overlooked. And again, kudos on the consistency. It might be just practicing the excerpt multiple times, or it might be the bigger mouthpieces at the end, but the last couple of examples sounded the best on this round.
