Chicago metal outfit Bongripper deals in all things heavy. If it's a style of rock that features heavy riffs, and tons of bass, the band has probably indulged in it at some point across the five albums its released since '06.
The group has just released a new unmastered single on its Bandcamp titled "Fisting," and the track has a pretty climatic progression. It all starts with a noisy, ominous drone. Eventually, doom-bringing riffs start pounding away in the mix just before the band breaks into blast beats and a heavy sludge metal groove.
Stream the track above. Hopefully, this track is some sort of teaser toward a full-length album. I'd certainly be looking forward to that considering how much I dug the band's last album.
