If you liked Janelle Monáe video, Tightrope, then you need to check out Sam & Dave.

Here’s the incendiary Hold on I’m Coming

and the sweet slow sound of When Something is Wrong with my Baby

and I haven’t even included the often imitated, never duplicated, Soul Man.

If you want to know more, you can read a little about Sam & Dave at Wikipedia or here at Ta-Nehesi Coates blog at The Atlantic. You can get what looks to be a great book, Amazon.com: Sweet Soul Music: Rhythm and Blues and the Southern Dream of Freedom by Peter Guralnick that goes into things at depth.
