Yesterday, the AC/DC social media channels became active for the first time in almost two months, igniting questions about whether the band was coming back. Today, we have more of a tease of new adventures for the band. The band has a new website, newsletter, and further updates to its social media, all centered around “PWR/UP.” Could it be a new song? A new album? Whatever it is, this “electrifying” development has us intrigued.
