Well, I stand corrected on not being able to play the blues about computers. Check out dot com blues
You also sing the blues about Tuition with "Tuition Blues"
Jimmy Smith is one of the originators of the Soul-Jazz organ-guitar-drum trio thing. Also has great gospel influenced jazz going on "The Sermon." This album is a sort of resurrected Jimmy Smith with a variety of big blues names like BB King, taj mahal, etc. I have one of his other new cds called "Damn!" which is appropriate, because he rocks.
