Seeing as this thread is predominantly about fiddling, I would check out historic recordings of Northumbrian fiddlers such as Ned Pearson, Adam Gray and Geordie Armstrong on Spotify.

And then listen to Andrew Cadie, a young contemporary exponent of the same tradition: https://music.apple.com/gb/album/half-witted-merry-mad-northumbrian-fiddle-music-from/1540246526

Great examples of solo fiddle playing.
