Nier Gestalt and Replicant Piano Collections is my favourite album. They're piano versions of songs from Nier Gestalt/Replicant, aka from the same series as Drakengard. I linked the whole playlist of the album
Search up anything from the Nier soundtracks.
Somestand out tracks from this album:
Grandma
Kaine
Song of The Ancients
if piano isn't quite your forte (heheh music joke), there's also the actual compositions from the OST itself which are more full of diff instruments and vocals
edit: im a HUGE gigantic mega fan of this album btw. the way the pianos are mic'ed up in these recordings is
so impressively intimate. you can legit feel and hear the wood of the piano creaking, as well as the pedals and the keys being depressed.
it's
gorgeous
