Avenged Sevenfold has been awarded two platinum album statuses from the RIAA (Recording Industry Association of America) for both 2010's Nightmare and 2013's Hail To The King. Platinum status for an album means the album has sold over 1 million copies.
As for new Avenged Sevenfold, they're working on it! The band recently posted a video from the studio teasing new material, though vocalist M. Shadows has made it clear there won't be a new album until touring can happen.
"It doesn't make sense for us right now to put out a record and not be able to tour it. The world has changed. Putting out a record on Spotify without touring for a rock band, it just doesn't make sense to us. So we're gonna wait till everything is back, then we'll come out with the record, finish it up, and all will be good."
As far as how the album will sound, Shadows has previously stated that the new material sounds nothing like their 2016 album The Stage.
"The record sounds nothing like The Stage — it's a completely new direction, and it sounds nothing like anything we've done. That's all I'll say about it: it's over the top, and it's very eclectic and wild."
