The Minnesota Orchestral Association has cancelled or rescheduled all concerts through April 7 due to the ongoing labor dispute.The orchestra's musicians have been locked out for four months. Management agreed to a new financial analysis, which the musicians have sought since the beginning of negotiations, but the terms of that analysis have yet to be agreed upon. "Realistically, we are all aware that it will take some time to complete this review....If we are able to come to an agreement within a timeframe that allows us to reinstate some of these concerts, we will make every effort to do so," board chair Jon Campbell said in a statement released Friday.

"There is absolutely no reason we could not return to the stage under some sort of temporary agreement and continue to perform while and simultaneously doing the independent financial analysis," said musician spokesman Tim Zavadil. "Certainly we hope they have not agreed to the analysis so they can prolong the lockout."

Cancelled performances include Beethoven's "Eroica," the Gershwins' "Here To Stay," "Four Last Songs" by Strauss and Josefowicz Plays Stravinsky. The announcement comes two days before the Grammy Awards. The orchestra's recording of Sibelius' Symphonies Nos. 2 and 5 is one of five nominees under best orchestral performance.

In a response statement, the musicians said the concert cancellations have "further eroded the public trust" and challenged management's intentions: "While continuing to build the $52 million Orchestra Hall lobby, with $14 million coming from taxpayer dollars, this latest set of cancellations through April 7 includes 10 Young People's Concerts, as well as a week-long residency serving the community of Bemidji. Through these cancellations, Management has taken another step toward throwing away the entire Orchestra season, leading us to ask, 'Was this the plan all along?'

The statement continued: "Management has lobbied for and received nearly $1 million in state support for music education and outreach, and this latest round of cancellations brings the total number of lost Education concerts to 18. If Orchestra Management fails to keep its commitment to the community by continuing to cancel education and outreach concerts, we ask 'Will taxpayers demand a refund?' "

Concerts rescheduled to be presented during the 2013-14 season beginning in September are YP: Supersonic Sounds, Common Chords: Bemidji and Trey McIntyre/ Preservation Hall.

Max Raabe and Palast Orchester, scheduled to play April 7, will now do so on that date, but at the Dakota Bar and Grill.

All ticketholders to concerts through April 7 will be contacted by the orchestra to go over several options. They may also handle it online at minnesotaorchestra.org/change.
