Music royalty will gather in Los Angeles on Sunday for the 51st annual Grammys but despite a dazzling star line-up, few big labels are throwing the glitzy after-parties of yesteryear given the recession and industry’s years-long malaise.

Some industry watchers even think the Grammys, which have seen viewership slide, need a facelift to revamp several award categories and change the show’s format to stay current with a generation of fans who have long bypassed mainstream music events.

“The Grammys are looking pretty long in the tooth when you consider the fragmentation of the music culture” said Robert Thompson, professor of culture at Syracuse University.

As usual, the broadcast will be performance-heavy, featuring best album nominees; best new artist nominees Adele and the Jonas Brothers; and veterans such as Paul McCartney and U2.
The night’s top contenders are rapper Lil Wayne with eight nominations and British rock band Coldplay with seven.

The economic crisis is just the latest insult to the music business which has lost its groove and 33 percent in U.S. album sales since 2000 amid a faster-than-predicted shift to digital distribution. But despite all the gloom and doom, the beat goes on. “A lot of people have in the industry have been beaten up in the past few years although the art form is vibrant,” said Mike McGuire, analyst with Gartner.

“We have to find a solution to the economic woes, but this is still a celebration of the artistic product, whether people are buying it or not,” said entertainment attorney Jay Cooper.

 Coldplay’s “Viva La Vida or Death and All His Friends,” is vying in the best album category against “In Rainbows” by fellow British rockers, Radiohead, which bypassed major labels to distribute the album on its own Web site at a price to be determined by consumers. It later released the album through a small label owned by rocker Dave Matthews.

Another indie release is considered the favorite: “Raising Sand,” an acclaimed collaboration between former Led Zeppelin rocker Robert Plant and American bluegrass singer Alison Krauss, while two rappers are also vying for the prize: Lil Wayne with “Tha Carter III” and Ne-Yo with “Year of the Gentleman.”

The album of the year is just one of 110 categories, with prizes to be given out in such genres as country, pop, reggae, bluegrass, polka, blues and spoken word. All but a dozen awards are hurriedly handed out before the main event kicks off at 8 p.m. EST (1 a.m. GMT Monday)

Richie Sambora is back, and apparently sober.

Just two weeks after an arrest for drunk driving,the lead guitarist for Jersey rock band Bon Jovi was back to his old self Wednesday night during a concert in downtown Los Angeles.

About mid-way through the packed show, lead singer Jon Bon Jovi singled Sambora out to the crowd, calling him his dear friend as fans cheered wildly. Bon Jovi then left the stage while Sambora, sporting black leather pants and a black top hat, played guitar and sang lead vocals on one of the band’s best-known ballads, “I’ll Be There For You.”

While it wasn’t Sambora’s first show since his arrest, it was a sort of homecoming for the Jersey boy who has made the area his home. The guitarist, and ex-husband of Heather Locklear, was arrested in Laguna Beach on March 26, apparently with his 10-year-old daughter in the car.

All that seemed far away on Wednesday night, though, as the band plowed through three decades of hit songs to a crowd of thousands.

And Richie never missed a beat.
