MINNEAPOLIS — Another attempt to break the long impasse in the Minnesota Orchestra lockout has failed.

Both sides said back-channel talks broke off after they were unable to agree on how to move forward. The last meeting was Monday.

Doug Kelly, one of the two management negotiators, said his side floated the idea of a reconciliation task force to discuss a vision for the future of the organization.

But one of the two musicians’ representatives, Tom Zavadil, said management just kept going back to talking points.

The musicians have been locked out for more than 13 months. Managers said they need substantial cost reductions from the musicians’ contract to make the orchestra financially viable into the future. Musicians said lower wages will send talented players elsewhere.
