Guns N' Roses have kept their promise to release an album soon - frontman Axl Rose has already laid down enough tracks to fill three records.
The band left fans waiting more than a decade for their last release, which finally hit stores in 2008, 15 years after work began on the record.
Rose is rumoured to have spent $13 million (£8.1 million) putting together the album, which would make it the most expensive record of all time.
The group vowed not to take as long on a follow-up, and guitarist DJ Ashba has revealed Rose has already recorded a mountain of new music.
He tells Australian radio station Triple M, "(Rose) has a lot of great songs up his sleeve. He probably has three albums worth of stuff recorded.
"He just sits down at the piano and plays. I'm like, 'This is amazing. People have to hear this song.' And he's like, 'Ah, this is something I'm tinkering on'. He's just a genius when it comes down to music and I just cannot wait to sit down with an acoustic guitar and just write. He's just got this gift that's very, very rare."
