Amid fizzling sales and dwindling business, the music industry responded with a Grammy show thick on collaborations, stirring performances and once in a lifetime moments.
Robert Plant and Alison Krauss took home the most hardware, but the night's performances provided the bulk of this morning's Grammy water cooler conversation. If you need a refresher, you can find images from these unforgettable moments in our Grammy gallery or skim through some of our favorite moments:
• U2 show off their new "Boots" — The band jumpstarted the Grammy telecast with the first single from No Line on the Horizon.
• Jennifer Hudson's triumphant return — After a year of unimaginable personal tragedy, Hudson returned to the Grammy stage for a breathtaking performance of "You Pulled Me Through." It's hard to imagine there was a dry eye in the house (or among the millions of viewers at home).
• McCartney and Grohl revisit the Beatles — The night before the 45th anniversary of the Beatles debut on the Ed Sullivan Show, McCartney and Grohl showed that "I Saw Her Standing There" can still electrify a room.
• Coldplay and Jay-Z — An intimate performance of "Lost" took on a new urgency when Jay hit the stage.
• Radiohead & the USC marching band — On a night full of remarkable guest spots, Radiohead went above and beyond recruiting the USC Trojan Marching Band for a rousing performance of "15 Step."
• J.T. & the Reverend — A last minute add to the Grammy lineup, this rousing rendition of "Let's Stay Together" — which also packed in Boyz II Men and Keith Urban — simply soared.
• Taylor Swift & Miley Cyrus — A stool, a guitar and a little help from a friend was all Swift needed to turned the Staples Center into a cozy little coffee bar with her deeply personal performance.
• Neil Diamond gets "Sweet" — Hail the man who can get an arena full of industry cynics to chat "bah bah bah" during the undeniably infectious "Sweet Caroline."
• Kanye and Estelle remind us that less is more — The night's "Rap Pack" summit certainly boasted star power, but Kanye's performance with Estelle through the sultry groove of "American Boy" was arguably tighter, brighter and more stylish.
• Adele & Sugarland — With "Stay" and "Chasing Pavements," British soul met Nashville twang on the common ground of yearning and heartbreak.
• New Orleans rising — Whoever decided to put Lil Wayne, Allen Toussaint, Terence Blanchard and the Dirty Dozen Brass Band on the stage at the same time deserves a medal.
• The Jonas Bros. & Stevie Wonder — We're still trying to wrap our heads around this one.
