Brazilian metal fan Murilo Martins had learned every riff from all of IRON MAIDEN’s 16 studio albums.

That’s right, Murilo has learned every riff from the band’s 1980 self-titled debut up until their most recent album, The Book Of Souls. Riffs from 155 songs, played in one take. It’s a feat as heroic as climbing up the highest mountain, isn't it? Yes it is. Give him a medal with Eddie's face on it, someone.

“I wouldn't be able to live with myself if I hadn't went through with this idea that had been in my mind for a long time,” says Martins. “Up the Irons!”
