These tracks reveal the dexterity of mood in Artie Shaw's bands—songs like “Temptation” and “The Skeleton in the Closet” see the sound switching on a pin between dramatic tension and lighthearted pomp, Shaw's velvety clarinet cruising in and out of the scene with an elegant nonchalance. “Beyond the Blue Horizon” jumps from an adagio opening into a peppy step in no time.
