Metallica to Perform with Classical Pianist Lang Lang at 2014 Grammys
It is unknown what song or songs they will perform together. It's not the band's first offbeat collaboration.
It's also not their first time dabbling in the world of classical music, as fans of 1999's symphonic live album "S&M" might recall.
Recording sessions for the band's long-awaited follow-up to 2008's "Death Magnetic" will also be halted for a March run of concerts in South America.
"When we're locked away in the studio," the band announced via its website. "We like to break out from time to time to gain some inspiration from you and all the love we feel when we go on the road."
A summer tour of Europe has already been set.
Metallica has already announced that a new song will be part of its set lists in 2014.
