Slapshot formed in Boston, Massachusetts in 1985 from the remnants of Negative FX and DYS, with vocalist Jack 'Choke' Kelly as the band's most recognizable figure. At a moment when many first-wave Boston hardcore bands were drifting toward crossover thrash, Slapshot doubled down on the raw speed and directness of the original Boston sound, and their debut Back on the Map (1986) helped sustain the scene's identity through the late 1980s. The band's straight-edge lyrics and uncompromising stance made them influential well beyond the United States, particularly in Germany and Belgium. After nearly four decades of intermittent activity, Slapshot announced their farewell tour in 2025.

A Fort Worth, Texas band forged in 2024, Slashed to Bits operate at the savage intersection of black, death, and thrash metal — a triad that prioritizes venom and speed over any single genre's orthodoxy.

Slaughtbbath is a black metal power trio from Santiago, Chile, formed in 2002, whose discography spans numerous demos, splits, and EPs before their debut album Hail to Fire (2013) and second album Alchemical Warfare (2019), both released on Hells Headbangers Records. The band toured North America in 2017 alongside fellow Chilean labelmates Communion and recorded Alchemical Warfare at DM6 studio in Santiago with Pablo Clares.
