Pac Div: "Black Acura" [feat. Mac Miller & Raven Sorvino]

"Show out for the girls and get your ass whipped / on some 8th grade right in front of the class shit"

I totally slept on Pac Div's debut last year but have since been playing catch up via the stray single here and there. This one's the best I've heard so far, nimble wordplay over rumbling-yet-unobtrusive shoegaze beats. This one is from the upcoming GMB album.

Mr. Muthafuckin' eXquire: "The Message"

Mr. Muthafuckin' eXquire up on that cloud rap tip. Biggest head scratcher on this one is the non sequitur "Dopeman" sample. Actually, even stranger is that, while this is a mere 2.5 minute song (pretty common in the age of internet freebies), eXquire is through rapping by the 1:30 mark. Always leaving 'em wanting more, I guess.

Aquarian: "Motherisk"

Aquarian's Soundcloud is not exactly frothing over with generous samples or biographical info, so I can't tell you a lot about the Toronto lad, but according to URB (from which this was cribbed; respeck) his debut EP - out in October - will be released on the stellar UNO NYC label, although once again there's no fucking mention of the dude signed to the label.

The Flaming Lips: "The First Time Ever I Saw Your Face" [feat. Amanda Palmer]

Yeah, this song already had a video once... but if you'll recall Erykah Badu took grievious exception to what she deemed "shock" tactics (wonder just what in the fuck she was thought was going to materialize while she was watching the band film it). So nearly three months later we get a recut video sans Badu's (frankly kinda homely) sis, Nayrok, and in comes Amanda Palmer of the Dresden Dolls. Same basic theme, except instead of viscous, blood-colored fluids this time Palmer is frolicking around [still nude] in a tub full of plain old vanilla flavored water. Still NSFW if the above image didn't already get you fired.

Converge: "Aimless Arrow"

At which point does "math rock" become "meth rock"?

Trick question: they were the same thing all along. Certainly helps to be rendered spastic if you're going to jam to the likes of Converge, who return here after an absurd three year layoff with the first cut from their forthcoming All We Love We Leave Behind. Wait a minute, wasn't that the name of a fucking U2 record?

Airhead: "Black Ink"

Airhead implies something flighty and inane, but homeboy's "Black Ink" is a focused blend of old school IDM glitch and modernist post-dubstep. Fuck, is it possible to come up with descriptors without sounding like a pretentious douchebag? Probably, but not if you are in fact a pretentious dbag like yours truly (that's post-douchebag if you're nasty).

Just listen to the fucking joint already.

Illum Sphere: "H808ER"

Tripping off that Daft Punk Tron vibe, this is some percolating, bass-saturated shit right here. Illum Sphere   isn't floating around a lot of information about himself (their selves?) but the act comes from Manchester and will be releasing the "Birthday" / "h808er" 12" digitally on September 3 and on vinyl September 10 through Young Turks.

Mouse on Mars: "They Know Your Name"

Mouse on Mars sound here like they were attempting to flirt with dubstep but are just too fucking weird to properly pull it off. They even throw in some uncharacteristically poppy half-rapped, half-sung lyrics. Wrrrd.

Bleeding Rainbow: "Pink Ruff"

This comes off like a less saturated My Bloody Valentine, which is a common enough touchstone in 2012 but represents a good look for this Philly quartet. "Pink Ruff" is the title track from their upcoming album which comes out in - damn! - January? For real?

And lest you think you were the first to draw the LeVar Burton references, yes, the band used to be called Reading Rainbow. Them ceast and desists are a motherfucker.

DJ Rashad: "Kush Ain't Loud"

If footwork evolves and hangs around long enough to become a permanent fixture on the EDM scene, DJ Rashad's Teklife Vol. 1: Welcome to the Chi could very well become the ur-text all other footwork is assembled from. Shit's like a Rosetta Stone of skittering beats and wobbling bass, and "Kush Ain't Loud" is arguably the man's magnum opus to date.
