You've just stumbled on the best kept jazz secret of the 21st century: the "Still Fresh" CD by the Four Freshmen.
Even if these guys never opened their mouths, their creative musicianship alone deserves attention. When you add their vocalizations, rooted in 50 years of that unique harmony, to this most recent collection of modern charts, the results are stunning.
You owe it to yourself to give "Still Fresh" a spin. My particular favorites are "Where Do You Start" and "Close Enough For Love" but the whole package is ear candy.
Then tell the world about it...but hurry because the Freshmen are back in studio working on their next CD.
