Folk legend Arlo Guthrie [ tickets ] has plotted out nearly a year of tour dates, with the next batch rolling out alongside his televised performance in the Pete Seeger birthday concert on PBS July 30.

The tribute concert--held May 3 at New York's Madison Square Garden--will air July 30 as a special edition of PBS's "Great Performances" series, and features more than 40 artists, including Guthrie, Bruce Springsteen, Joan Baez and Dave Matthews. Seeger, a folk music icon, turned 90 in May and performed Woody Guthrie's "This Land Is Your Land" with Bruce Springsteen during the Obama inaugural celebration.

Arlo Guthrie--Woody's son, recently had a birthday as well, turning 62 on July 10. Per Guthrie's website, his birthday was preceded by the annual "Summer Revival," a three-day benefit for the Guthrie Center that takes place at the old Trinity Church in Great Barrington, MA, where the movie "Alice's Restaurant" was filmed.

In a recent post on his website, Arlo--who has never shied away from a political opinion in his music or speech--lashed out at the Iranian government for its efforts to monitor and block communication via social networks in the aftermath of the country's recent presidential election.

The election results overwhelmingly favored incumbent conservative candidate Mahmoud Ahmadinejad over challenger and reformist candidate Mir-Hossein Mousavi. Mousavi challenged the results citing irregularities in the vote process, and increasingly violent confrontations between authorities and protestors supporting Mousavi found a worldwide audience via the Internet, prompting a clampdown on Internet communications emanating from Iran.

Guthrie announced in late June that he was taking part in an online protest to make it potentially more difficult for Iranian censors to filter online messages. "I am changing the location of some social networks (Twitter & MySpace etc.) to Tehran, Iran for the purpose of giving the Government there one extra address to wade through as they sneak around spying on their own people," he wrote.

"You guys wearing sacred clothing, holding the Holy Koran in hand, while your thugs beat, maim and kill your fathers, brothers, sisters & mothers - Yeah you guys (if you're reading this) - You have shown the entire world that you would sacrifice your own children for your temporary authority over them even as you KNOW you will grow old and pass away, and they will live to create a world of their own. The only question is how many will perish before you come to your senses or stand before your creator... How much blood will be spilt before your shame overcomes you and you shed tears for forgiveness? If the power of your authority comes only from clubs and guns, what does that say of your God? It would be better to have no faith than to have as little as yours."
