Metallica bassist Rob Trujillo has revealed that the band are itching to begin work on their follow-up to 2008's Death Magnetic.
"There's no shortage of riffage in Metallica world right now," says Trujillo. "I'm super-excited. I know that we've got another couple of records in us. I think it's only gonna get better."
The band will return to the UK in July to headline Sonisphere.
