Quite a few interesting and mostly little known 20th century pieces on Daniel Stachowiak's YouTube channel. The recording quality isn't always marvellous, but his playing is pretty nifty. Here are some I particularly like:
Eric from GuitarLoot
Renaissance and Baroque freak; classical guitars by Lester Backshall (2008), Ramirez (Guitarra del Tiempo 2017),
Yamaha (SLG 130NW silent classical guitar 2014).
