Looks like Arte Macchina is in the process of making their first PV for an upcoming release! Details have not been announced yet, but at least it looks like they're finally releasing something (which may or may not be live-limited). Check out exclusive shots provided by the owner of the warehouse here. The band has also released a comment video, which also shows the PV in progress.
Also, it seems that their website is down, as a 403 forbidden page pops up...their social media accounts, however, are still active.
