Snoop Dogg [ tickets ] backs his recently released album, "R+G (Rhythm + Gangsta): The Masterpiece," with an early 2005 swing through the U.S.

Fellow rapper Chingy [ tickets ]--whose latest album, "Powerballin'," landed in stores in November--is tentatively scheduled to join Snoop on several dates, though specifics have not yet been hammered out, according to Chingy's publicist.

Winners will be named during the 47th Annual Grammy Awards ceremony, which takes place in Los Angeles on Feb. 13, and will air on CBS television.

In addition to recording and touring, Snoop has also taken on the role of radio disc-jockey, and now hosts a monthly rap program--dubbed "Da Church"--on XM Satellite Radio. The 90-minute show is re-aired several times each month. A full schedule is posted at Snoop's website.
