My goto is https://www.music-map.com. Some of my best finds ever came from there.

I did try out the OP's recommender. It seems to misunderstand which genres strongly fit the band.

Guadalupe Plata is super-gritty mex rockabilly but the AI slotted it as delta blues.

Darla Farmer's only album is story based prog - like The Dear Hunter w/ a Diablo Swing Orchestra tone. AI called it a "hazy, intimate vibe".

All Them Witches scored better but the recommendations were all bands I know (Colour Haze, King Gizzard, King Buffalo).

Very nice! One big past thread and 2 tinies, if anyone is curious:

Nice. I've been into Chris Luno for a while and closest is Aline Rocha, which fits pretty darn close and I have never heard of her.
