This Tuesday, July 13th, the date on which Brazil celebrates Rock Day, Iron Maiden released another mysterious teaser on their social media.

Less than a week ago, a video released by the band shows Bruce Dickinson inviting fans to "Belshazzar's Feast" on July 15th, next Thursday.

Some fans have been following clues left by Iron Maiden for the past few weeks and theorize that the big announcement could be the band's 17th studio album, which could be called Writing On The Wall . The theory originates from the fact that the Feast of Belshazzar is a biblical passage that tells the story of writing on a wall.

In the new teaser released by the band, an animated hand that appears to be that of the mascot Eddie is shown tearing a Belshazzar's Feast poster off the wall and revealing the letters WOTW – which could be an acronym for Writing On The Wall, fueling fan theories. Check it out:
