Louis Armstrong. The double-CD, 'Pure Louis', presents 28 of his all-time classic, from 'What a Wonderful World' and 'Hello Dolly!' to 'Blueberry Hill' and 'Ain't Misbehavin'. As always, his trademark trumpet is as sweet as are his gravel-laced vocals, with a little scat thrown in to boot. When Armstrong belts out standards like 'Cabaret' and 'When You're Smiling', you can almost taste the moonshine and cigars from a smoky, '30s-era, New Orleans speakeasy. Honey-tongued Queen of Scat herself, Ms. Ella Fitzgerald, joins Armstrong on hits like 'Let's Call the Whole Thing Off', 'Let's Do It', and the beautiful 'Tenderly'; other celebrated guests also make an appearance, including Billie Holiday and Trummy Young. Old Satchmo may no longer be around to lead his orchestra on 30-cities-in-30-days tour gigs, but his rousing jazz classics–and the feelings of pure joy that they elicit in listeners young and old–are alive and well.
