Don Devore, the former guitarist for the theatrical Philadelphia hardcore band Ink & Dagger, now leads the new Brooklyn band Sick Feeling. “Liberal Arts” is the first single from their forthcoming debut album Suburban Myth, and it’s a roiling blast of ranchor, all garbled screams and hammering rhythm-section onslaught. If you close your eyes when “Liberal Arts” plays, you can almost imagine how fucking violent those live shows are going to be. Give it a listen below.

A few months after he came home from a years-long prison stay in March, Baton Rouge rap hero Lil Boosie was planning to release a commercially-available album. He cranked out a ton of singles, but the album never came out. Maybe it never will. And now, all of a sudden, he’s got a new mixtape called Life After Deathrow out in the world. Whatever! Fine! I’ll take it! Boosie is a vivid, impassioned, powerful rap figure, and this is his first full-length statement in many years. It has a few guests — Trey Songz, Yo Gotti, Shy Glizzy — but it’s mostly just Boosie in attack mode. Check out the tape below.

Noctilucence refers to cloud-like formations made up of tiny ice crystals that shine bright in a deep twilight just after the sun has set. Although noctilucent clouds are fleeting by nature — they’re only visible at a certain time in certain parts of the world — Mark McGuire has harnessed the electric glow of clouds in a night sky in his video for “Noctilucence.” The 16-minute video shows viewers different landscapes at night, pausing on each one for a minute or two to let us view these scenes through the stationary camera. Within these wide shots, brightly colored textures bleed, flash, materialize, and disappear on screen as cars pass by, their headlights in focus then dissolving into black. Although the phenomenon of noctilucence isn’t shown in the video, there seems to be some kindred link between the mystique of Mark McGuire’s sound and this rare phenomenon. Watch.

After releasing the gut-kicking album INNOCENCE earlier this year, the brotherly Virginia psych-rock trio Pontiak (who are, full disclosure, friends of mine) are about to release a new limited-edition two-song 7″ on the small Portuguese label Revolve. The A-side is “Underneath Us Like A Snake,” a slow, ominous, synth-buzzing crawl. Give it a listen below.

Earlier this year, the iconoclastic Chicago singer-songwriter Willis Earl Beal left XL, his label, and threw himself into the chaotic, uncertain world of self-released records to get his Experiments In Time album out into the world. Valerian Zamel directed a video for Beal’s song “I AM.,” and it’s all smeary point-of-view shots, filmed from the perspective of a lonely figure wandering through a city at night and almost never interacting with everyone. It’s an ominous piece of work, and you can watch it below.

Today, Public Enemy announced that they will be reissuing deluxe editions of both 1988′s It Takes A Nation Of Millions To Hold Us Back and 1990′s Fear Of A Black Planet, which will include quite a few exclusive add-ons, including rare bonus mixes, instrumental re-workings, and essays by both Questlove of the Roots and Andres Torres of Wax Poetics. Additionally, the Nation Of Millions reissue will include a live performance DVD. Check out the extensive tracklists below.

Team Spirit, the Brooklyn garage-rockers led by the former Passion Pit keyboardist Ayad Al Adhamy, have built up an enviable catalog of goofy, fun music videos. Their new clip, for “Satisfaction,” might not be their best, but it still has the anarchic spirit of its predecessors. Director Alex Russek shot the video at New York’s storied Electric Lady studios, and the clip tells the story of the band’s dealings with a pill-popping, Rick Rubin-esque producer. Watch it below.

Chicago drill overlord Chief Keef may have lost his label deal, but when he gets together, he will still be a force on the mixtape underground. I have high hopes for the forthcoming Back From The Dead 2, the sequel to the tape that helped build Keef’s name in the first place. “Paper,” a track from that tape, has an uncommonly slurry verse from Keef’s incarcerated buddy Gucci Mane and a purposeful, fiery verse from Keef. It may be the first time Keef has ever outrapped Gucci on a song. Listen below.
