(CNN) -- The unlikely alchemy of a hard-rock legend and a bluegrass superstar created Grammy gold Sunday night, as Robert Plant and Alison Krauss picked up five awards -- including album and record of the year -- for their work, "Raising Sand."



Alison Krauss and Robert Plant's song "Please Read the Letter" won record of the year.



"Sand" won album of the year honor, while a song from the set, "Please Read the Letter," won record of the year.



"I'm bewildered. In the old days we would have called this selling out. But it's a good way to spend a Sunday," said Plant, the legendary Led Zeppelin front man.



"Raising Sand" was produced by T Bone Burnett, whose production and oversight of the "O Brother, Where Art Thou" soundtrack won three awards -- including album of the year -- in 2002.



For "Sand," Burnett selected several songs, mostly obscurities such as Gene Clark's "Polly Come Home" and Sam Phillips' "Sister Rosetta Goes Before Us," and let Plant and Krauss mix it up in stark, often subdued fashion.



The result was widely praised and reached No. 2 on the album charts.  Watch Plant and Krauss talk about their win »



The win adds to Krauss' eye-popping Grammy total of 26 awards -- more than any female artist in history and third only to conductor Sir Georg Solti (31) and producer-arranger-mogul Quincy Jones (27).



The awards were overshadowed by news that performer Chris Brown, who had been up for two Grammys, had become the focus of a domestic-violence allegation. Brown turned himself in to Los Angeles police Sunday evening.  Watch a report on the latest developments in the Brown case »

The argument escalated when Brown stopped the car and the woman got out, the LAPD said, citing the victim's account.



A representative for Brown at the ICM agency in Los Angeles could not immediately be reached for comment.



Coldplay took home one of the Grammys' big three honors, song of the year, for the title track of their album "Viva La Vida." The group also won best rock album.



"Thank you and sorry to Sir Paul McCartney for blatantly recycling the 'Sgt. Pepper' outfits," the band's Will Champion said, noting the group's colorful attire. See the stars on the red carpet »

Jennifer Hudson brought the house down with an emotional performance of a new ballad, "You Pulled Me Through," and won best R&B album -- an award presented by another big-voiced vocalist, Whitney Houston.



Hudson was equally emotional in her acceptance speech. "I'd like to thank my family in heaven and those who are with me today," she said, her voice catching. "Everybody, thank you all," she concluded.
