Labor Day has come and gone and that, of course, means summer is over.

Some people have already turned their thoughts to next summer.  Shawn Mendes' concert for Aug. 6 at Xcel Energy Center was announced Wednesday.

Now the third edition of the Eaux Claires festival has been announced for June 16-17 in Eau Claire, Wis. A limited number of “pre-sale” tickets will be available at 10 a.m. Friday.

What’s curious is the third weekend in June -- that would be the 16th and 17th next year -- is traditionally when the long-established Rock the Garden is staged by Walker Art Center and 89.3 the Current.

While Eaux Claires is the baby of Bon Iver’s Justin Vernon, the Current is something of a stepfather as one of the festival’s biggest supporters.

This summer, Eaux Claires, which favors indie rock, competed in July with the nearby Summer Set, a more eclectic fest with EDM, rock and hip-hop, in Somerset, Wis.

We’ve reached out to organizers of Eaux Claires III and Rock the Garden for comments; stay tuned.
