If you're looking for a straight, unfiltered shot of full-strength Chicago-style traditional jazz, this disc pulls no punches. Three of the four opening tracks are incendiary Commodore blowouts. Bob Haggart whistles during the opening and closing choruses of his own "Whistlin' the Blues," which comes as a bit of a breather after all that stomping. The next six selections were released on the Manhattan record label, available to the public as souvenirs to be purchased at Nick's Tavern, a hot spot for old-fashioned jazz in Greenwich Village. Four of these tracks feature the exciting baritone saxophone of Ernie Caceres, who exchanges a few words with Muggsy Spanier at the beginning of yet another whistling tune, "Feather Brain Blues"…
