Like the days of the week, the emergence of a new Elvis retrospective is a common occurrence that requires little in the way of parades, prime-time news coverage and fireworks. That said, Sony BMG's two-disc companion album to its successful singles campaign from 2005 is worth more than a short blurb. The blurb would state: "The King features 47 classics, two bonus live cuts and one dreadful remix" and it would be correct, but for each new generation the building blocks of rock and roll must be re-packaged, re-mixed and re-inserted into pop culture. Released to coincide with the 30th anniversary of The King's death, listeners will get "Don't Be Cruel," "Suspicious Minds," "Viva Las Vegas," "That's All Right," "Are You Lonesome Tonight" and "Burning Love." What they won't receive is "Blue Moon," but anyone with even the slightest hint of "cool" will have already picked up a copy of Mr. Presley's 1956 eponymous debut, so it's really not that big of a deal. For those just coming of age in 2007, this is the Elvis compilation you will purchase.
