The first batch of Grammy performers are regulars on stage and at the podium of the music industry's biggest night. They own 29 career Grammy Awards between them, and there are chances for more to come.
Metallica's James Hetfield and Lars Ulrichcould expand on the veteran rockers' eight previous wins with a nomination for best rock song ("Hardwired"), while seven-time winner Underwood is up for best country solo performance ("Church Bells").

And Urban, a four-time Grammy winner, collected another brace of nominations ahead of this year's gala (best country album for Ripcord and best country solo performance for "Blue Ain't Your Color").
