The Dave Matthews Band and Nelly are among the latest acts confirmed to perform during the 44th annual Grammy Awards ceremonies later this month. Also joining previously announced performers U2 and Alicia Keys will be a tribute to Mercury's "O Brother, Where Art Thou?" soundtrack by Emmylou Harris, Alison Krauss, Ralph Stanley, Gillian Welch, and the Soggy Bottom Boys (Dan Tyminski and Pat Enright). Nelly will join 'N Sync for the latter's "Girlfriend."

Hosted for the second year in a row by actor/comedian/"Daily Show" host Jon Stewart, the Grammy Awards ceremony is set for Feb. 27 at the Staples Center in Los Angeles, and will be broadcast live on CBS television.

All of the performers are nominated for Grammys, with U2 leading the field with eight nominations, including album of the year for "All That You Can't Leave Behind" (Interscope) and song of the year for "Stuck in a Moment You Can't Get Out Of." Keys has six nominations, including one for best new artist.

'N Sync is up for best pop vocal album ("Celebrity," Jive), and Nelly will vie for best rap solo performance ("Ride Wit Me") and best rap/sung collaboration ("Where the Party At" with Jagged Edge). The Dave Matthews Band is nominated for best rock performance by a duo or group for the single "The Space Between."

The artists taking part in the "O Brother" tribute all appear on the album, which is up for the album of the year honor, as well as best compilation soundtrack album for a motion picture, television or other visual media. All of the artists but Welch are currently on the road with the Down From the Mountain tour, which directly stems from the soundtrack's success.

In addition to the performers, Gloria Estefan and No Doubt's Gwen Stefani have joined the list of presenters, which already boasts Janet Jackson, Diana Krall, and Britney Spears.
