2010 will see Chicago hosting the 2nd annual US Sónar Festival between September 9th and 11th, and there’s a some things you need to know about it right now:

– It’s pretty much free

– Kid Koala is going to be there

– Everyone else so far sounds pretty dope, too

It’s free because the Chicago Department of Cultural Affairs is apparently awesome. Also, they’re holding it in “unusual venues” like the Frank Ghery designed Jay Pritzker Pavilion in Millennium Park on the 9th, and the Chicago Cultural Center on the 10th and 11th.

Now for the initial lineup: Kid Koala‘s outfit The Slew is going to sónar the hell out of us. Oval are gonna be there, too (they’ve got a new album coming out as well). Other acts announced include Ben Frost, Nosaj Thing, Dutchman Martyn, with more avant acts to include Nicolas Bernier + Martin Messier: La Chambre des Machines, a Canadian duo that base their show on rudimentary noise machines from the early twentieth century, and Lesley Flanigan, a New York artist who constructs her music with hand-made instruments and the sounds created by her own voice.

More acts are TBA, (I mean, LCD Soundsystem, Roxy Music, and Hot Chip played the festival in Spain this June), so for the most current full line-up information and rumored acts, please head over to our Festival Outlook page here.

And if you still want more of this next level business, Sónar is teaming with Adventures In Modern Music (AIMM), to bring you more shows throughout the weekend. AIMM will present shows at a great venue — the one and only Empty Bottle — featuring The Rhys Chatham Trio, Sleep and Efterklang, and others TBA. There will be an admission cost to these shows, and they can be purchased right over here.

The festival, which goes down September 3rd in the Los Angles Historic State Park, will feature the likes of The Rapture and Panda Bear as headliners along with the recently reunited Sleep, the not retired Ted Leo & The Pharmacists, !!!, Dead Man’s Bones, Unbroken, Man Man, Delorean, Ariel Pink’s Haunted Graffiti, AA Bondy, The Mountan Goats, Wavves, Best Coast, Abe Vagoda, School of Seven Bells,  Titus Andronicus, Warpaint, Magic Kids, Let’s Wrestle, and many, many more. For a full list of artists, click here.

Tickets for the festival are $20 in advance and will be available through Ticketweb.com.

For one, ATP New York has handed over the reigns to Jim Jarmusch, the legendary indie filmmaker whose resume results in a rather lengthy Wikipedia entry. The 57-year-old Akron, OH native, who has the task of following up 2009 curators, The Flaming Lips, will hand pick the Sunday portion of ATP. So far, that lineup includes Raekwon, Girls, Fucked Up, Vivian Girls, the Brian Jonestown Massacre, Wooden Shjips, and The Black Angels.

In the 48 hours prior Sunday, many others will perform at Kutsher’s Country Club in Monticello, NY. The previously announced Stooges (performing Raw Power), Sleep (performing Holy Mountain), Mudhoney (performing Superfuzz Bigmuff + Early Singles), and The Scientists (performing Blood Red River) will kick things off on Friday. Then, on Saturday, the likes of Sonic Youth, Explosions in the Sky, Fuck Buttons, The Breeders, The Books, Papa M, and Apse will entertain the lucky masses.

Many more artists are still to be announced. Plus, all three days will also feature DJs and movies!

Festival tickets are priced at $250 + booking fee for the weekend. Friday day tickets are priced at $110 + booking fee. Saturday day tickets are priced at $120 + booking fee. Sunday day tickets will be available in March. May we direct your attention to atpfestival.com for more ticket purchasing and more information. You better hurry, however. Total capacity is limited to 3,000 after all!

A few months and a plane ride across the Atlantic later, ATP’s New York incarnation, ATP New York, will return to Monticello, NY for its third edition.

The recently reunited Iggy & the Stooges performing Raw Power, Mudhoney performing Superfuzz Bigmuff, Scientists performing Blood Red River, and the also recently reunited Sleep performing Holy Mountain.

Of course, plenty acts for both events are still forthcoming. Tickets for All Tomorrow’s Parties are on sale here.
