According to the band's website, the concert tour will kick off March 28 at the Allstate Arena in Chicago, IL. 

"We want to thank everyone for hanging in with us for the last few months," said the members of Green Day on their website. "We are very excited to hit the road and see all of you again, though we regret having to cancel more shows." 

Armstrong, who appeared in Broadway's American Idiot, was treated for substance abuse following an onstage outburst at the September 2012 iHeartRadio Festival; performances following the festival were immediately postponed.

On the group's website, Armstrong added, "Dear friends… I just want to thank you all for the love and support you've shown for the past few months. Believe me, it hasn't gone unnoticed and I’m eternally grateful to have such an amazing set of friends and family. I'm getting better everyday. So now, without further ado, the show must go on. We can’t wait to get on the road and live out load! Our passion has only grown stronger."
