Robert Plant and Alison Krauss brought home 5 Grammys this year including best album for their work together on Raising Sand.

Plant said he had to relearn how to sing the works on the album and not include his normal fluttering style.

The two sang just prior to receiving the best album award which was presented by members of Greenday.

Plant said some might call it a sell out but he thinks of it as somthing to do on a Sunday afternoon.
