The Cromulent Shakespeare Company has posted their schedule of Shakespeare in the Park performances for this year. They're doing Troilus and Cressida a play that I know pretty much nothing about.
The Minneapolis Park Board has posted concert schedules for Bryant Square Park, Father Hennepin Bluffs Park, Lake Harriet Park, and Minnehaha Park.
One thing that they never seem to list in the Lake Harriet concert schedule is the Gilbert and Sullivan Very Light Opera Company performances. This year they'll be doing The Mikado on July 17th, and 18th. On the schedule it's listed simply as "Minneapolis Pops Orchestra".
