NEW YORK (Billboard) -- Wilco lead singer Jeff Tweedy is entering rehab to address an addiction to painkillers, a spokesperson told Billboard.com.
"The treatment follows a well-documented history of Tweedy's battle with migraine headaches," according to a statement released by the Chicago group.
The release of Wilco's new Nonesuch album, "A Ghost Is Born," has been moved from June 8 to June 22 "to accommodate Tweedy's recovery."
There is no word yet as to whether the band will be able to honor its upcoming tour plans, which include a May 1 appearance at the Coachella Valley Music & Arts Festival in southern California and a June 11 performance at the Bonnaroo festival in Manchester, Tenn.
Tweedy's struggles with migraines were on display in the Wilco documentary "I am Trying To Break Your Heart." In a key scene that illustrated his irreparable rift with since-departed band member Jay Bennett, Tweedy becomes sick to his stomach from a migraine while mixing the song "Heavy Metal Drummer" for the 2002 album "Yankee Hotel Foxtrot."
In Greg Kot's upcoming Wilco book "Learning How To Die," Bennett says the footage of Tweedy becoming ill is out of sequence; Tweedy insists it is not.
