Been on a Bela Fleck/Abigail Washburn kick cause I got a cheap ($20!!) banjo.
Also, found an old instructional video of him
Rhapsody in Blue
For anyone interested in mathy jazz / hip-hop, I cannot recommend this guy's channel enough:
TAYP - Devil's Pie remix
EDIT: and another sweet remix of that song by none other than Pete Rock himself.
