Willie Nelson is going to make us wait even longer for his first Twin Cities headline concert since 2002. His official website announced over the weekend that a week's worth of shows -- including those Friday and Saturday at Mystic Lake Casino in Prior Lake -- have been postponed until October due to an "unanticipated scheduling conflict."

Mystic Lake entertainment director Joshua Flom said he wasn't given an explanation about the conflict, but the rescheduled sold-out gigs are Oct. 8-9 (with March 26 tickets honored for Oct. 8, March 27 for Oct. 9). Refunds will be available at place of purchase until July 31. Nelson's new album, "Country Music," produced by T Bone Burnett, is due April 13.

In other concert news, Patty Griffin and Buddy Miller team up on June 19 at the Fitzgerald Theater; the super trio of Bela Fleck, Zakir Hussain and Edgar Meyer is set for June 28 at the Guthrie; and Pieta Brown does the "Quiet, Please" series at the Varsity on June 4. Tickets to all three concerts will go on sale Friday.
