In love with the soundtrack

Hey everyone! I just finished marathonning this entire game. It is definitely one of my favorite games ever. it made me laugh, it made me cry and it made me angry.

but the thing i loved most about the game was the soundtrack. especially the tracks by Syd Matters.

so I was wondering does anyone know any similar artists/music tracks. also very feelgood (or sad) acoustic songs with alot of guitar and raw voices?
