Used to have a good buddy who was really into tori amos and could play a lot of her songs. Hope hes doing alright.

The 11 minute version of heard it through the grapevine cover by ccr where they just jam the hell out for the last half of the song

Or any instrumental by northlane. I like his vocals too but the instrumental just feels so good

Edit: Or maybe for longevity go with somrthing like the blue danube waltz or requiem in d minor
