• Beginning Thursday, the Portland Museum of Art opens its summer blockbuster, “John Marin: Modernism at Midcentury.” Most research and exhibitions about Marin focus on his early work. This show, with 54 paintings, drawings and watercolors, concentrates on the late period of Marin’s career, from 1933 through his death in 1953.

The show will be up through Oct. 10.

Curators hope the exhibition will add to our understanding of Marin’s work and help re-establish his reputation as an artist committed to developing a modern visual language of landscape and place in an era preoccupied with abstraction. The exhibition includes work on loans from the Museum of Fine Arts, Boston; Museum of Modern Art, New York; and the National Gallery of Art, Washington, D.C.

Marin came to Maine in 1914, and returned almost each summer of his life after that.

Summer theater

• Fresh off a successful run of the musical comedy “Avenue Q,” Ogunquit Playhouse opens the hippie-era musical “Summer of Love” on Wednesday. Michelle Lee, star of TV’s “Knot’s Landing,” plays a lead role in this show.

The musical features the songs of the late 1960s by The Mamas and the Papas, Donovan, Janis Joplin, Jefferson Airplane and others. It is on stage in Ogunquit through July 16.

Roger Bean wrote the show. His name may be familiar, because he also wrote “The Marvelous Wonderettes,” which is on stage through Saturday at the Maine State Music Theatre in Brunswick. In that show, the pop songs of the 1950s and ’60s take center stage.
