Query: A singer in his prime

I've collected Johnny Rivers' music since the early 1960's and watched his styles change over the years. What other singer has mastered such diverse styles as blues, rock'n'roll, country, ballads and so on always with first class backing musicians?Recorded in the legendary Sun Stuios in Memphis, this album is Johnny performing at his very best. Somehow, he has managed to capture and re-create the simplicity and honesty of the early rock'n'roll masters like Elvis and Jerry Lee Lewis.This is one of the worlds great performers doing what he does best.
