I think the label has been bought, and I don't remember by whom so i'm not sure if they changed the name, but Hyperion has released a LOT of cds with his music, as has Brilliant Classics (which I think released a box set?)
Damn I've never heard of this composer before you've been taking about him. Like 1-2 month ago me would've not known who this is lol. Thank you for sharing this with us! :D
You should definitely look into Alkan! He's very underrated but has found a lot of fame in modernity because of pianists like Hamelin, Maltempo, Jack Gibbons, and Ronald Smith. I have a video of his Concerto for Solo Piano which is arguably his most famous work. His Le Festin d'Esope is also very much worth checking out too :)
