They may be a product of the early 1990s, but the members of Pantera have reached a milestone that’s so 21st Century: The band has surpassed 1 billion streams.

The achievement, announced Tuesday by Pantera’s social media manager, is based on the number of streams across Amazon, Google, Spotify, Apple and Deezer.

Rex Brown, who played bass for the now-defunct band, says reaching the 1 billion mark is especially sweet because Pantera always had trouble getting radio airplay. “We were the biggest underground band of the ’90s,” Brown says. “We didn’t have a lot of MTV support, we didn’t have any radio play.

Now you go to any sporting event and hear one of our songs at a football game, which is great, but they wouldn’t touch it back then.

So we just kind of flew by the seat of our pants and kind of D.I.Y., and just toured our butts off and worked really, really hard.”
