Experimental Everything
40 Bands/80 Minutes! (Sounds Are Active, $10.98) documents a Monday night all-ages show at Los Angeles’ ll Corral (a former sweatshop), where 40 bands each played two-minute sets. Covering everything from post-hip-hop (Bizzart vs. Demonslayer) to sludge metal (Harassor) to sheer insanity (Explogasm, Rape Nick Lachey), it’s a glimpse into the anything-goes mentality of L.A.’s experimental rock underground. Notable moments include a “performance” from local Rob Williams, who makes a complex ham sandwich with his feet, and the cathartic last show from The Wives. Some bands pack enough pretentiousness in two minutes to make Thurston Moore blush, but the film is ultimately charming, making one wish more shows were this concise. Josiah Hughes

Grime Time
The Lord of the Mic series is organized like a boxing match, where UK grime’s youngest, hungriest MCs face off in three rounds, with a bonus final fight. Highlights of the nine battles on Lord of the Mic II (Hot Headz Ent., £8.99) include a bugged-out set of freestyles from Earz, and a dramatic, obscenity-filled session between the murderous Demon and lanky, humorous Bashy, who spends time sucking on a lollipop when not spitting (literally) at the camera. Hosted by lovable stoner Jammer and filmed entirely in dark basements, the flick captures the gritty aesthetic and the wild passion of grime, although only the staunchest bwoy on road or the most serious avant-rap nerd will make it through all 105 intense minutes.

Techno Fever
Living for the weekend is bittersweet, a point that Feiern (Intergroove, $26) drives home. With candid, touching interviews about life, love, and loss–and jerky montages that simulate how your eyeball sees in low-light, Ecstasy-drenched states of mind–this German documentary strives to articulate the fragile skeins that bind avid clubbers together. Although it’s not overly professional (you can see people’s mic clips, the club scenes tend to go on too long), the 80-minute Feiern is a charmingly intimate portrait of a few Berliners (Villalobos and Luciano, among them) recounting the most memorable club moments of their lives. Be forwarned: the film is in German with English, French, and Spanish subtitles–best not to watch when you’re too fucked up. Vivian Host
