This set brings together all the jazz and R&B instrumentals that reached the R&B charts between 1942 and 1963 and draws a connecting line between Swing, Bebop, Boogie, Jive, Mambo, Rock'n'roll, culminating in the funky organ grooves of Booker T and Jimmy Smith. It still has the irresistible energy that seduced so many in the Forties, Fifties and Sixties and changed the character of popular music forever
