I suppose he was in Holland before, at least he recorded with flutist Mark Alban Lotz
Yes, he did indeed.
It's stated in this link
https://www.journalventilo.fr/identites-remarquables-javier-campos-martinez/I summarize and translate : he took part to masterclasses in Amsterdam and Rotterdam, where he was invited by Mark Lotz, and settled down then in Paris in 1990.
And he's now based in Marseille (he was at least last year, as the article was written). The link I gave you is of a culturel "webzine" in Marseille.
BTW, I happen to know (virtually) the lady who wrote the article.
That's all for today, folks.
Stay safe and have a nice weekend everybody.
