All levels. This recording ?FEELS GOOD.? Nothing beats the "thumpin" sound and feel of the Hammond B-3 Organ. People from the great Jimmy Smith to Joey De Francesco have demonstrated it?s unique ability to swing hard! Now, for the first time, you can take advantage of the opportunity to play along with two of Jazz?s finest, Hank Marr and Jimmy Rupp. Once you try it, you?ll be hooked! The song selection is perfect for the organ, as many have an inherent ?bluesy? sound. You?ll find playing lyrically much easier and you?ll love the heavy blues flavoring. Don?t miss this one!
