This week

• Harpswell artist John Bisbee will discuss his “Two Tons” installation at the Ogunquit Museum of American Art at 7 p.m. Tuesday.

The installation is on view through Aug. 1.

Bisbee, who teaches at Bowdoin College, constructs large, abstract sculptures from 12-inch steel spikes, which he welds together to create massive, patterned pieces. This installation is his first exhibition at the museum. His talk is part of a busy summer at the museum.

Also on view through Aug. 1 is “Selma Koss Holtz: A Legacy of Giving.” A reception will be held from 5 to 7 p.m. Sunday.

Other Tuesday-night talks at the museum include “Art of the Word: Four Poets and a Guitar” on July 27. New Hampshire poet laureate Walter Butts and his wife, Stephanie, will be joined by Portsmouth poet laureates Mark DeCarteret and Mimi White. Chris Volpe will accompany on acoustic guitar.

On Aug. 3, museum director Ron Crusan will moderate the discussion, “Reminiscences: The Ogunquit Art Colony 1945-1970.” A panel of artists will share memories of Edward Betts, Robert Laurent, Henry Strater and other artists.

On Aug. 10, Maine architect Carole A. Wilson will lead a discussion of the film “KoolhaasHouselife,” which also will be screened. Wilson studied with the renowned Dutch architect Rem Koolhaas.
