If you're headed to M.I.A. at the Palladium tonight, get there early: Cool Kids have cancelled, but we're dying to see what C440R's monster party-rap duo have in store when they step in tonight as a last-minute opening act. Big Digits at the Palladium: who'da thunk it? For an idea of how much awesomeness is in store, check the video above to see what happened the last time someone offered TD and Mac Swell a nice big stage.

Monsterous edition of THUNDERDOME tonight, bringing Baltimore Clurb legend Scottie B and Spank Rock's Chris Rockswell to the decks, along with resident headbangers Micl Ptvn, Mistaker, and DJ Die Young to represent the home team. Special live-video guests: Robotkid (ask him how much the new Harmonix game Rock Band is gonna rule) and Matt Boch.

DOWNLOAD: Shepherdess, "Not Gonna Be There Now" (mp3)

For reasons that aren't entirely musical, Hilken Mancini was our favorite member of Fuzzy. Chris Toppin was technically the better singer, but Hilken was the one with the squeaky voice, the messy guitar, and the skintight jumpsuits.

We have a general rule: hippies and sequencers don't mix. But, as blog nerds have discovered via the already-web-famous track "World with No Windows," Crystal Understanding’s Aaron and Sonya have become a weird, sweet exception. The duo is aligned with the local shit-pop cabal Compound 440r, and like most C440r groups it forsakes (sez their bio) "the usual trappings of rockitude, replacing guitars and basses with handmade claves, computerized beats, and power feelings."

VIDEO: U.V. Protection, "Animals"

Thanks again to everyone who sent along videos for Best Music Poll. We tried to get them up on the ballot page, but the ballot page wasn't having it. So we're gonna try rolling them out OTD-style. If we're lucky, clicking above will get you the awesome video for UV Protection's "Animals," which reminds us of something by Numbers, although it turns out UV Pro have never heard Numbers.

Regular readers of OTD know we're all over Mark E. Moon's jock. Up til now he's focused on dropping Certified Bananas-style indie-rap smashups, but in honor of his joining the MySpace megaverse -- as good an excuse to revisit his way-too-slept on Neutral Milk Hotel remix -- he's put together a two-minutes-and-change minimix that throws gimmicks out the window and just kills shit, flipping the ubiquitous Justice/Simian track "We Are Your Friends" until it flips the bird at social networking.

Baddassery over at the Midway Cafe in JP courtesy of the "Musk" crew. We don't really have words to describe Kocho Bi-Sexual's track "Donuts." Gratuitously dubby DIY Casiotone reggaeton jam that rhymes "dog shit" with "bong hits"? We're all over it. Best thing to come out of Detroit since "Sandwiches."

DOWNLOAD: DJ Mark E. Moon, "Kidzmix" (mp3)

In case you missed him spinning at the Children’s Museum a couple of weeks ago, DJ Mark E. Moon — the nom de guerre of a prominent local cartoonist/indie-rocker/party-rocker — has uploaded an ingenious mixtape that brings the anything-goes strategies of 2ManyDJs and Hollertronix to the Kidz Bop crowd.

We try to keep abreast of MICL PTVN's adventures in this space, but the dude just keeps on keeping ahead of us. David Day caught up with him in his latest circuits column, and then sent us the following mixtape to pass along:

Potvin's sense of tunes and danceability is no clearer than this mix, "Disco mix 4 Sarah," which does the hip Manhead, Daft Punk, Pitchfork poster-girl Annie, club queen Miss Kittin, those LCD boys, and the red-hot Digitalism remix of Cure's "Fire In Cairo" in one 60-minute super-jam.

We're so turning our entire weekend over to Compound 440r. Mr. MicL Potvin just checked in to inform us of a late-breaking gig by Japanther Friday night over at MIT. Which is sort of like just casually mentioning that there's gonna be a fucking hurricane in someone's living room. Oh, the furniture damage. For those of you who attended the Steer Roast, this is the same address: 70 Amherst Street, 9 pm.

That dude DJ Mark E. Moon has been awful quiet lately -- too quiet, buried-in-the-lab quiet, building-birfday-mixtapes quiet. We should've known that he wasn't kidding when he told us his Dipset-ized Neutral Milk Hotel "King of Karat Flowers" remix was part of a longer suite. But after that, there was his baile-funk Belle and Sebastian remix and then .

The latest denizens of Boston's powerbook-pop underground to join the mysterious Compound 440r collective, the Westward Trail are not without precedent in these parts. Their pre-owned synthpop tones play nicely with We Are Cassette, and in a budget crunch they could probably go halfsies on a guitar player with Mobius Band or Certainly, Sir.

OTD is back. (More soon on gators, Disney, and the genius of Southwest Florida radio.) And just in time, because the fishwrap told people to come here today for the new Big Digits track, which of course you all are fiending for because they're about to wreck shop with Hot Chip and the aforementioned new dance-punk geniuses on the block, Blanks.
