Arcade Fire singer Win Butler is "recovering nicely," according to a post he made on the Arcade Fire website.In late March the band had to cancel dates after Butler became ill. He had sinus surgery and is now preparing for a U.S. tour that begins April 26. While resting he and his wife, bandmate Regine Chassagne, began working on new material."I wanted to let you all know that the surjery was successful, and I am recovering nicely," Butler writes. "Thank you all for your thoughts and emails…I will probably start singing again this week some time to try and get ready for the shows in North America.It has been a blessing in disguise to be forced to stay home and read, and sleep (pick up Cormac Mcarthy’s “The Road” if you are feeling like a little post apocalypse…don’t let the Oprah Book Club Sticker scare you away)… Regine and I have even started working on some new songs…Anyway see you all soonLuv Win"Here are the group's upcoming tour dates, as posted on Pitchfork:Arcade Fire, allergic to wintertime:04-26 San Diego, CA - Spreckels Theatre04-28 Indio, CA - Empire Polo Field (Coachella)05-01 Atlanta, GA - Atlanta Civic Centre Theatre *05-02 Asheville, NC - Thomas Wolfe Auditorium *05-04 Washington, DC - DAR Constitution Hall *05-05 Upper Darby, PA - Tower Theatre *05-07 New York, NY - United Palace *05-08 New York, NY - United Palace *05-09 New York, NY - Radio City Music Hall (High Line Festival) *05-10 Boston, MA - Orpheum Theatre05-12 Montreal, Quebec - Arena Maurice Richard !05-13 Montreal, Quebec - Arena Maurice Richard !05-15 Toronto, Ontario - Massey Hall ^05-16 Toronto, Ontario - Massey Hall ^05-18 Chicago, IL - Chicago Theatre !05-19 Chicago, IL - Chicago Theatre #05-20 Chicago, IL - Chicago Theatre #05-24 Vancouver, British Columbia - Deer Lake Park !05-26 George, WA - The Gorge (Sasquatch!
