These after-the-Grammys parties capped a week of celebrations leading up to Sunday night's awards show.

The biggest of them was Clive Davis' annual pre-Grammy bash, which he dedicated to Whitney Houston just hours after her death. Houston, a multiple Grammy winner, was preparing for the Davis party when she was found dead Saturday afternoon in her Los Angeles hotel room.

Sunday night's galas included the EMI Grammy After Party at the Capital Records Building in Hollywood, where guests included Beach Boys Brian Wilson and Mike Love, guitarist Slash and British songstress Corinne Bailey Rae.

The Warner Music Group teamed up with InStyle for a Grammy celebration at the Chateau Marmont in Los Angeles. Among the guests there were Bruno Mars, John Legend and Nicole Richie.
