Popped hardcore is what Silverstein is all about. With a squeaky-clean burst of stylized tantrums, the Canadian six-piece spills out over the sides with pre- and post-teenage tensions. The group’s 2015 release, “I Am Alive in Everything I Touch” is a bar-chord survey of post-hardcore emotions. Mannered bursts such as “Heaven, Hell and Purgatory” and “In the Dark” mainstream once-underground cretin hops for post-“Dookie” soul-searching, with time-honored builds and releases. Though the album is polished and tightly executed, Silverstein is a band that is best experienced as live, interactive engagement. You can see it in proper context when the group headlines a night of slam-dance bonding Friday, Oct. 21, at the Canal Club. On the bill will be the one-for-all-and-all-for-one sounds of More to Monroe, Underdog Champs, Savage Hands and Dens. The all-ages free-for-all begins at 6 p.m. Admission is $15-$17. thecanalclub.com.
