Code Red Riot (Saturday, 6 p.m.) Fuse the radio-friendly sensibilities of bands like Foo Fighters and Chevelle with traditional songwriting and Las Vegas swagger, and you’ll get Code Red Riot. The hard rock quintet’s latest single, “Living Low” straddles the happy medium between the catchiness of Breaking Benjamin and the heaviness of Godsmack—making them the perfect support act for Las Rageous. facebook.com/coderedriot

A Friend, A Foe (Friday, 6 p.m.) The band’s punishing, downtuned metalcore—with staccato breakdowns in contrast with catchy, extended singing passages—has allowed it to rock both DIY spots (see: house shows and Eagle Aerie Hall) and more traditional rooms (Vinyl at the Hard Rock Hotel, the Roxy in LA). AFAF just released an EP, The Risk in Playing It Safe, which expands on its melodic tendencies, not unlike Rise Against. facebook.com/afriendafoe

We Gave It Hell (Friday, 6:25 p.m.) We Gave It Hell calls itself a metal band, but the ethereal melodies and clean vocals at the start of latest single “Conversations at the Edge” veer from the guttural yells and heavy chugs all too common in modern iterations of the genre. The quartet is no stranger to big crowds; the band rocked Extreme Thing in 2013 and ’14, and it has shared the stage with metal vets After the Burial and Atreyu since. facebook.com/wegaveithell

Nations (Saturday, 6:25 p.m.) At a glance, Nations separates itself from other bands on the bill because it has two vocalists: a singer and a screamer. That makes for high-energy shows, in which songs like the rambunctious “Dirty Fire” come off in a new light. With a new album set to debut in the coming months, there’s no better time to catch this metalcore quintet. facebook.com/nationsbandofficial
