Yes you can watch Avenged Sevenfold live on October 27th on your phone! The band is playing a once-in-a-lifetime show that will stream live in 360-degree virtual reality! You can get details from the band HERE and even more specifics about the event HERE.
More importantly, it sounds like they will make some announcements on the much-expected new album during the show as well. The new album is rumored to be titled "Voltaic Oceans" and is also rumored to be released on December 9th. There hasn't been an official announcement about any of this, contrary to what you'll read on Wikipedia, but it does seem an awful lot like they'll talk about it at this show.
