I have listened to a(nother) album of jazzy arrangements of video game music: https://the8bitbigband.bandcamp.com/album/press-start
Verdict: it's good!
Favorite arrangement: Zelda's Lullaby. Just inject that 5/4 straight into my veins
Least favorite arrangement: Lonely Rolling Star. It's not bad, but I'm just not sure this tune is well suited to the big band thing
