The list of Grammy performers keeps growing, with Macy Gray, Sheryl Crow, Jill Scott, Shelby Lynne, Moby and Blue Man Group joining 'NSYNC, Christina Aguilera, Destiny's Child and the hotly anticipated Eminem-Elton John duet on the lineup.

Gray is up for three awards — Record of the Year, Song of the Year and Best Female Pop Vocal Performance for "I Try," from her On How Life Is release.

Seven-time Grammy winner Crow will perform with Lynne, whose leap last year from straight country into Memphis soul earned her a Best New Artist nomination. I Am Shelby Lynne finished #5 in the recently announced Village Voice "Pazz & Jop" critics' poll.

Moby, Scott and the popular performance artists Blue Man Group will perform together. Scott is up for three awards, while Moby's "Natural Blues" is up for Best Dance Recording and Blue Man Group are nominated in the new Best Pop Instrumental Album category for Audio.

The Grammys also announced Wednesday that "TRL" host Carson Daly, Sisqó, Gloria Estefan and Tony Bennett have joined the show's list of presenters. The awards will be held on February 21 at the Staples Center in Los Angeles, and will be broadcast live on CBS from 8-11 p.m. ET. ('s parent company, Viacom, also owns CBS.)
