Lollapalooza (Chicago). New Orleans Jazz & Heritage Festival (New Orleans). Bonnaroo (Manchester, Tennessee); Austin City Limits (Austin, Texas).

Those are the four major summer music festivals in the United States that YouTube, in partnership with Dell, will be live-streaming.

What you can expect: multiple live channels, behind-the-scenes content and exclusive artist interviews. Says Robert Kyncl, global head of content for YouTube:

“As a platform, YouTube is committed to bringing original content and unique music experiences to fans, artists, and festivals in a way that benefits the entire music ecosystem”.

And where does Dell come in, exactly, you ask?

Well, the company will be supplying Dell Precision workstations to support the live and recorded video feeds from the festivals.

They’ve already been put to the test. Austin City Limits and Lollapalooza’s video production team have already used Dell Precision workstations at the 2011 festivals to produce video extras to support and surround the live broadcasts.

At SXSW, YouTube will today host a panel on “How YouTube Festival Webcasts Changed the World” (3:30pm CDT at the Austin Convention Center).
