My band is playing "Your Mind Is On Vacation" by Mose Allison and, being new to the band (and being an inexperienced player generally), I'm working on learning it. It's a jazz/blues fusion tune with a straight but rapid bass line. What would be a good mode to use to improvise moving bass lines like the DB player does in the video? I think minor pentatonic, which I'm most familiar with, wouldn't be up to the complexity of the piano part which seems to be using more jazz-influenced progressions. Many thanks!
