Machine Gun Kelly, Black Keys square off for Grammys

State of play: The Black Keys have earned 16 Grammy nominations during their career, including two for "Dropout Boogie."

• This is Machine Gun Kelly's first nomination, which he earned for 2022's "Mainstream Sellout."

Of note: The other artists nominated for Best Rock Album are Ozzy Osbourne, Elvis Costello, IDLES and Spoon.

What they're saying: Machine Gun Kelly was so excited about his nomination back in November that he saved the envelope his name was printed on.

• "I'm a hoarder. So, this is going to stay in my house forever," he told Entertainment Tonight after the nominations were revealed.

The intrigue: Recent recipients of Best Rock Album range from established bands like Foo Fighters and The Strokes to newbie Greta Van Fleet.

Quick take: The smart money is on The Black Keys or an icon like Osbourne, but stranger things than Machine Gun Kelly winning have happened.

How to watch: The Grammys air at 8pm Sunday on CBS and stream on Paramount+.
