Spencer Kaufman, Loudwire Green Day were planning to head up the 2012 Voodoo Music + Arts Experience over Halloween weekend, but given singer Billie Joe Armstrong ‘s recent entry into rehab for treatment of substance abuse issues, they’ve now bowed out of the performance. The timing has not been the best in the world for Green Day, as the singer’s meltdown at the iHeart Music Festival in Las Vegas and subsequent rehab announcement came just ahead of the release of the group’s ‘¡Uno!’ album. At the time, the band issued a statement apologizing for the incident at the Las Vegas event, revealing Armstrong’s decision to attend rehab, and regretfully announcing that some of their promotional appearances would be postponed as a result. Drummer Tre Cool issued the band’s statement on their exit from the Voodoo Experience. It read: Canceling shows is something we rarely do. We never want to let our fans down, and we are grateful for all of you being understanding during this time. Meanwhile, Voodoo Music + Arts Experience organizers, Rehage Entertainment, issued their own statement on the matter. It read: We, like everyone, were looking forward to having Green Day back at Voodoo. Their 2004 performance was one of the festival’s greatest. We are obviously disappointed in the news, but realize the health and well being of Billie Joe is the most important thing right now. We wish him and the entire Green Day family the best and offer them our full support. The Voodoo Experience will go on without Green Day. The festival runs Oct. 26-28 at New Orleans’ City Park. Even without Green Day, the lineup is pretty solid. Neil Young & Crazy Horse, the Avett Brothers , Justice, Silversun Pickups , AWOLNATION, Jack White , Skrillex , and Coheed & Cambria are among the top performers on this year’s bill.
