Phil Collins’ very beautiful trackYou Know What I Mean.
It does have a little bit of strings as garnish.
Only a dream - Mary Chapin-Carpenter
Bridge over troubled water - Simon and Garfunkle
I’m a big fan of Spencer Krug. He’s part of a number of small bands, but also records under a “solo” project. This album in particular is just him singing while playing the piano: Jagjaguwar::JAG222.
