If you could only own 7 Jazz/blues albums. What would they be?

Tough one, maybe I'll go with.....

Danny Gatton & Buddy Emmons.  Red Neck Jazz Explosion
Grant Green.  Solid
John Mayall.  A Hard Road
Duke Ellington.  Far East Suite
Coleman Hawkins. Body and Soul
Sonny Rollins  Saxophone Collossus
James Booker.  Lost Paramount Tapes

This isn't a list of the seven best jazz and blues records in my collection.  It's an attempt to answer your question.  I'd want a nice mix of jazz and blues, guitar, piano, and sax, up tempo and slow, melodic and challenging, etc.  This could do the trick.

Schubert

Song For My Father was my last title out before the cut.  It's a great record IMO (better, in a vacuum, than Lost Paramount Tapes), but wasn't quite the stylistic fit for my collection.  Cool choice, tho.
