This is a nice recording of swing and blues style guitar. Lots of fun to listen to -- like sitting in on a friendly jam session. Duke Robillard really shines on "Avalon" and the bluesier numbers and Herb Ellis sounds like he's having fun throughout. Recommended for swing fans or those new to jazz guitar.
Output:
Positive
