Jazz Play-a-long tracks for the Bb Blues and F Blues

My new favorite site for jazz karaoke is Grooveshark.  I plug in the search for "Aebersold" and instantly I have like 100 play-a-long back up rhythm section tracks for a wide array of jazz standards.  

Here is your assignment...Go to the Vol. 54 Maiden Voyage album and play with F Blues and Bb Blues.  Remember, the more you play along, the more comfortable it's going to be.  Before you know it, you'll have a goatee and call your girlfriend "man," as you lay down the heavy bebop.
