The 22-track "Ultimate" follows the 2001 release of the single-disc "The Very Best of Prince."

A week before Prince's new NPG Music Club/Universal album, "3121," hits stores on March 21, Rhino will unveil a two-disc collection of remastered hits and remixes. The 22-track "Ultimate" follows the 2001 release of the single-disc "The Very Best of Prince," which has sold 1.2 million copies in the United States, according to Nielsen SoundScan.

Beyond must-haves such as "I Wanna Be Your Lover," "I Would Die 4 U," "Controversy," "Sexy Mutha" and "Purple Rain," the album includes the NPG remix of "Cream," an acoustic version of "7," dance mixes of "Little Red Corvette," "Let's Go Crazy" and "Pop Life," an alternate mix of "Gett Off" and extended versions of "Kiss" and "Hot Thing."

As previously reported, Prince will perform as the musical guest Saturday (Feb. 4) on NBC's "Saturday Night Live." He will also join his newest musical protege, Tamar, for a show tonight at New York's Nokia Theatre. Tamar's debut, "Beautiful, Loved and Blessed" is expected to hit stores the same day as "3121."

Later this year, Tamar will serve as the opening act on Prince's world tour, dates for which have yet to be announced.
