The whole album is great, though some tracks are weirder than others. Although it is Hal Wilner's baby, the actual artists on each track for this album are various and sundry. Details can be seen at the Amazon page here.
I have seen B.B. King live, and Buddy Guy too, but I never saw either Albert King or Stevie Ray Vaughan live. That clip is from their "In Session" album, which is available at Amazon as a CD/DVD.
That movie would be absolutely nothing without its soundtrack. Samuel L Jackson singing the blues? Enough said.
I love "Duck" Dunn. He's one of my biggest influences. You're right, he did record with Albert King but this, however, is Gus Thornton. This video is from a great recording called In Session (sometimes with '83 at the end.) This makes a great stocking stuffer!
Almost anything by Louis Jordan. Jordan was one of the most popular entertainers in music history, but he has been largely forgotten (by white audiences, anyway). Jordan was popular because his music was fun, joyous, and full of humor. Stylistically, he played with a small, taut 5-person band toward the end of the swing era, and some of his compositions can be considered early proto-rock.
I'd suggest you start with The Best of Louis Jordan, particularly:
Saturday Night Fish Fry
Caldonia
Beans and Cornbread
Five Guys Named Moe
Knock me a Kiss
Get her the cd from the Blues Masters Series, Harmonica Classics.
I learned to play the harmonica in college by listening to that CD.
