The rock-a-billy style of Elvis Presley came out of his own roots in the southern United States.

Now, his fans are set to get 'All Shook Up' over a new 4-CD compilation detailing the entire recording career of 'The King of Rock-n-Roll.' The collection is being released to coincide with what would have been the King's 75th birthday, next month.

Elvis may have left the building, but he never left the hearts of his legions of fans.

To mark the King of Rock's 75th birthday next month, RCA/Legacy is releasing a 4-CD compilation, 'Elvis 75: Good Rockin' Tonight.' The collection includes 100 digitally restored tracks including hit singles, rare cuts, live performances, and all 30 number-one songs such as 'Heartbreak Hotel', 'Hound Dog', 'Jailhouse Rock' and 'Suspicious Minds'. The set also features a 7-thousand word essay by music critic and historian Billy Altman, along with many rarely seen photographs.

Altman says unlike previous 'Best Of' compilations, this one contains the rock legend's entire career.
