There are a few of his Frescobaldi interpretations on Youtube, two toccatas and a canzona among them. There is no reason to deny his dexterity, and the canzona is most charming, but his toccatas lack direction and integrity IMO.
I sense there's a lot to explore and enjoy here and I expect my appreciation will grow as I listen more.
In the booklet Moulin says that
Les toccate montrent une nouvelle manière d’écrire pour le clavier. Improvisations couchées sur le papier, elles se réclament d’une seconda prattica. Comme Caccini ou Monteverdi pour la voix, a n d’émouvoir, l’on joue con afetti cantabili et l’on use des passi ou passagi, grands effets de doubles croches. Le tactus s’assouplit pour mieux exprimer les sentiments, « comme pour dépeindre les mots d’un madrigal sous-jacent » nous dit Frescobaldi. Musique dramatique qui révèle un improvisateur génial.
This is very much how I hear Frescobaldi, so it was a pleasure to read, but I'm not totally sure that Moulin has translated this idea of improvisations into music. He may have done, I don't mean to cast an aspersion, I need more time with the performances. Toccata 10 Bk 2 sounds a bit linear - without the dramatic contrasts which you might expect from word painting the text of a madrigal. It's all somehow a bit too polite, more polite than I'd normally associate with the idea of "Musique dramatique qui révèle un improvisateur génial." More French than Latin possibly.
Is that « comme pour dépeindre les mots d’un madrigal sous-jacent » a quote from one of Fresocbaldi's prefaces?
The harpsichord sounds lovely, it's is an original creation by a factor called Philippe Humeau, which he says was
Motivé par le claveciniste François Guerrier qui me donna des mots que je devais transformer en sons, je lui construisis cet instrument.
I shall check out this François Guerrier, he's recorded some Forqueray. I imagine a poet-Keyboard player, what were these words he gave? Like Rimbaud's poem Voyelles maybe

He uses a virginal, also rather nice sounding, for some of the pieces.
Despite all of this, there's a lot of things to enjoy and explore in the recording, I don't want to sound as though I'm knocking it.
