As part of the second-ever Independent Label Market—an event which will host a number of independent imprints selling “a combination of new, old, and exclusive releases” on North 6th Street in Brooklyn this Saturday, October 8—XL will be releasing a limited 12″ single of Portishead‘s “Chase the Tear.” Although the track has been floating around in digital form since 2009, the song has yet to see a physical release until now, and, furthermore, it will come with a new version of the song by Toronto’s Doldrums on the flip side. There will be 200 signed copies available at the Independent Label Market this weekend, with the single seeing a full release November 14, and all proceeds going to help Amnesty International. Considering “Chase the Tear” (which, we should say, uses tear as in “to tear a piece of paper”) came out over two years ago, you may have forgotten what the tune sounded like, so we’ve gone ahead and provided the video for the track below.

Bubblin’ Up UK bass head Guy Andrews is set to follow up his solid Your Notion EP for Discobelle with a fresh two-track 12″ record for Untold’s Hemlock imprint. The Brighton-based producer will release “Shades” b/w “Textures,” two intensely percussive club jams, on November 7.

Several big albums are dropping this month, yet it seems like none of them have received the pre-release accolades being showered upon Glass Swords, the debut full-length from Scottish producer Rustie. The LP officially drops on October 10 via the esteemed Warp label, but a stream of the entire album premiered earlier this week on The Guardian UK music blog. The stream is posted below, so give it a listen and dig in to the hyperactive electro-synth-bass madness that lies within.

It was unfortunate news that the Red Bull Music Academy had to withdraw from hosting this year’s events in Tokyo in the wake of the devastating tsunami, but things started looking brighter once Madrid was named as the new locale RBMA 2011 would inhabit. Now, with the announcement of the first round of events scheduled to take place in the Spanish capital, the excitement has jumped a notch. Artists set to appear between October 23 and November 25 include Global Communication (performing the excellent 76:14 LP in full), Matias Aguayo, Mathew Jonson, El Guincho, Frankie Knuckles (pictured above), Ghosts on Tape, Mannie Fresh, Tiger & Woods, Krystal Klear, Modeselektor, Doc Daneeka, Clams Casino, and xxxy, among many others. You can find more information about the month-long string of musical events at RBMA Madrid here, and keep your eyes peeled, as RBMA promises that more events will be announced in the weeks ahead.
