favourites of mine in the folk category:

• Solas an Lae - The Light of the Day by Eoghan Ó Ceannabháin & Ultan O'Brien A simple combination of a powerful voice, beautiful fiddle and some really moving songs. https://eoghanultan.bandcamp.com/album/solas-an-lae-the-light-of-the-day

And if you like that there's also:

• The Deepest Breath by Eoghan Ó Ceannabháin https://eoghanoceannabhain.bandcamp.com/album/the-deepest-breath

Also worth checking out:

• Anything by Lankum: The first folk band I got into on bandcamp, aka the start of a terrible addiction. They play traditional music with entirely their own style. Pulls your head and feelings all sorts of ways. Some of it is quite bleak but all of it is great. https://lankum.bandcamp.com/

But if by folk you were specifically thinking of the Scottish smallpipes then of course you want this incredible album:

• Carry Them With Us by Brìghde Chaimbeul https://brighdechaimbeul.bandcamp.com/album/carry-them-with-us
