As young'uns grab the gold, it's not the 'Grannies' anymore

JENNIFER LOPEZ, Rihanna and Katy Perry did pay heed to the new CBS fashionista-police edict, keeping breasts (mostly) and bums safely under cover, darn. The often "slit down to there" J. Lo let only one shoulder and one very long leg out to play.

Still, there was plenty of youthful zip (if not sex appeal) at Sunday night's really big Grammy music awards - one unlikely to be miss-tagged "The Grannies."

While driving at 55 (th annual), it was hard to spot old-timers in the winner's circle - save Bonnie Raitt (in the "Americana" category) and two-time jazz winners Chick Corea/Gary Burton - as relative new kids on the block like Frank Ocean, Gotye and fun. walked off with multiple honors.

Latin star Juanes, Adele, Carrie Underwood, Zac Brown Band and Beyonce also got props.

The old-school/new-school R&B surfing Ocean, a critics' darling and social landmark for boldly outing himself, hasn't moved all that many albums as yet. But winning the Urban Contemporary album Grammy for his impeccably crafted "Channel Orange" debut could jump-start sales. Ocean also shared in the Rap/Sung collaboration with Jay-Z, Kanye West and The Dream for "Church in the Wild."

The stripped-down, dynamic blues rockin' Black Keys claimed Best Rock album ("El Camino.") Their track "Lonely Boy" took both Rock Performance and Rock Song honors. The Keys' co-leader Dan Auerbach also was named Producer of the Year and helped New Orleans music legend Dr. John to top blues- album prize for "Locked Down."

Underscoring pop radio's newfound embrace of organic music (and Internet buzz), the sensitive new-age Belgian ruminator Gotye scored Record of the Year and the Pop Duo award (with Kimbra) for the YouTube spread (and knocked off) "Somebody That I Used to Know." The lanky dude also got you good with Best Alternative Music album for "Making Mirrors."

Need more proof that acoustic rock's revived? Mumford and Sons capped the victory parade with Best Album of the Year for "Babel."

Another overnight sensation (only 12 years in the making), fun. mined both New Artist and Song of the Year honors, the latter for "We Are Young," a soaring pop anthem that sounds like a 21st-century Queen. We can remember when fun. was happy just playing the North Star (Fall, 2009) and earning a Daily News profile.

And here's yet more evidence that the Grammys are a-changing.

While the most eccentic and jazz-laced of bands competing in the R&B album category, Robert Glasper Experiment stole that plum away with "Black Radio" from the likes of R. Kelly and Anthony Hamilton. 'Twas a shock even to the band leader who called his troupe the most "unpopular or less known" in the bunch, and to Willingboro, N.J.'s delighted Derrick Hodge, bassist in the group.

Even in the hard-rock-metal category, usually dominated by fogies, the relative baby band Halestorm stole the brass from heavies like Megadeth, Anthrax and Iron Maiden.

Especially early on, Grammy-show performances were likewise focused on and to "the youngsters" - opening the night with an Alice in Wonderland-themed Taylor Swift chasing away the Mad Hatter (and yet another bad boyfriend), then a carrot-topped Brit Ed Sheeran harmonizing (kinda sorta) with big "fan" Elton John on Ed's massively watched and downloaded paean to a prostitute, "The A-Team." And how about that delightful, singing-in-the-rain exhortation to "Carry On" by the well named fun.?

But in his much-hyped singing-career comeback, Justin Timberlake seemed to be equally courting the older, Buble-loving crowd, tuxed-in with a retro black and white look and walloping big band that stayed "organic" even when Jay-Z hopped up on stage to rap.

Another much anticipated tribute segment to Bob Marley proved more about "influence" than his repertoire, as both Bruno Mars and Sting served up reggae-laced tunes of their own, then brought on Caribbean-born Rihanna and Marley offspring for a rousing "Could You Be Love."

Philly artists were pretty much left on the cutting room floor this year. The twice-nominated Temple University Symphony Orchestra flunked out - ditto pop-vocal-album contender Pink.

Cherry Hill's Cristin Milioti had a piece of the Best Musical Theater album ("Once"). And while "Undun" in the Rap album race (losing to Drake), The Roots could claim a big piece of Jimmy Fallon's win for the music-centeric Best Comedy Album "Blow Your Pants off."
