One of the greatest albums of the 20th century, that's a fact... -- Another No. 1 for Mr. Wonder -- If the 1920's had rock stars, they would have all been like this guy...

5/21/1971 (47 years ago today) - Marvin Gaye releases his 11th studio LP, the beyond-phenomenal "What's Going On" -- Justifiably regarded as one of the landmark recordings in the history of pop music, "WGO?" was really a concept album made up of just nine songs(!), telling the story from the point of view of a Vietnam vet returning to the country he had been fighting for, and seeing only hatred, suffering and injustice. It's quite a revelation to hear these songs now, and realize how meaningful they remain, almost half-a-century later. It's really sad, the way we humans treat one another.

5/21/1977 (41 years ago today) - Stevie Wonder starts three weeks at the top of the chart with "Sir Duke" -- His tribute to Duke Ellington is Stevie's sixth No. 1 U.S. single. 'Catchy' doesn't even begin to...

5/21/1904 - Born on this date, Thomas Wright "Fats" Waller, jazz pianist, organist, composer, singer, and comedy entertainer whose innovations in the "Harlem stride style" of keyboard-playing/boogie-woogie pretty much laid the groundwork for modern jazz piano -- Best known for the classics "Ain't Misbehavin'" and "Honeysuckle Rose", Fats was a superstar in the mid-1920's, as in "Can you top this story?": In 1926, Waller was kidnapped at gunpoint in Chicago and driven to club owned by notorious mob boss Al Capone -- Once inside, he was ordered to perform at what turned out to be a surprise birthday party for the gangster! Yikes! Fats passed away from pneumonia-related causes on December 15, 1943; he was only 39 years old.
