I got hold of a copy of the 3CD Cherry Red compilation The King of Rock'n'Soul The Atlantic Sessions (1962 -1968) by the mighty Solomon Burke . A whopping 79 tracks for your listening pleasure
If truth be told it is a bit difficult to get your teeth into and I would not recommend listening to it all in a oner.
I've a couple of cheap and cheerful compilations of post Atlantic stuff along with his brilliant 2002 covers album Don't Give Up On Me on Fat Possum and his Country Soul album Nashville where his voice is deeper and richer
I was not that familiar with his earliers stuff.The Cherry Red website states that it
There are some fillers and some bog standard tunes but a few crackers as well. You could go for quality over quantity and have an excellent single album on your hands.
