Pitchfork Music Festival 2009 will rock Chicago’s Union Park with global indie stars on three stages July 17-19.

For its fourth official year, Pitchfork is gearing up to deliver three days of forward-thinking programming and a fun and comfortable experience at a reasonable price for some 45,000 attendees from the U.S. and other countries.

Among the long (and growing) list of bands and artists scheduled to perform are Built to Spill, The Jesus Lizard, Yo La Tengo, Yeasayer, Doom, The National, Vivian Girls, M83, Grizzly Bear, Pharoahe Monch. Tortoise, The Walkmen, and countless others. Veteran psychedelic rockers The Flaming Lips will close out the Festival Sunday night.

New this year – fans determined Friday evening’s set lists when early ticket buyers voted on each band’s songs they’d like to hear as part of a new series titles “Write the Night: Set Lists By Request.” In addition to stellar music, this great event also features vendors, specialty fairs, and activities which promote Chicago’s arts community.

Pitchfork is family-friendly – kids under the age of 10 admitted free when accompanied by an adult – and will take place rain or shine. Biking to Union Park (1501 W. Randolph) is encouraged, and bike parking will be provided.
