“We Make Better Art When We Make Art Together” is the June installment of “Quiet, Please,” a free, monthly speaker series at the Malden Public Library.

The talk coincides with the Malden Sketch Group’s 12th annual exhibit, at Commerce Place, 350 Main St., Malden, through June 20. “Quiet, Please” is a monthly series of talks at the Malden Public Library about arts, cultures and other interesting things. It’s hosted by Greg Cook of Malden, an arts reporter for WBUR.org and The Providence Phoenix newspaper.
