The logo for Cavalera Conspiracy was recently spotted in a field in England, as a crop formation. You can see the story here, on a site devoted to crop circles and other mysticism.
Since they first started appearing with great frequency and getting covered in the media, many idiots have asserted that crop circles are the work of aliens or other paranormal beings. The truth, of course, is that they're the work of drunks and other pranksters.
Cavalera Conspiracy's second album, Blunt Force Trauma, is out now and available in stores everywhere.
