Duck Dunn was a Master.
I suppose I could (perhaps should) just leave the post there.
But, one indication of “Mastery” is the execution of something that sounds simple, but is quite the opposite. To me, this line is one great example.
One of my gigs is a Blues Brothers Tribute act. This tune is on the playlist. It doesn’t sound like anything much more than a somewhat spirited 12 bar. Until you start trying to cop that dotted 1/8th rhythm with the right hand at the tempo.
The Duck executes it with fuel in the tank and, of course, 200 proof groove.
If there is a technique “trick” to it, I haven’t found it. Back to the shed on this one for me.
