The Medford Family Network continues its seven-concert summer series with a performance by a surprise musical guest.

In addition to music, dancing, movement and sing-a-longs, there will be open art activities, free books and community information.

Activities take place from 5 to 6 p.m., with the concert from 6 to 7 p.m.

The remaining MFN concerts in the series are on August 14 (Matt Heaton and the Outside Toys) and August 21 (Ben Rudnick and Friends), both at the Condon Shell.

In case of inclement weather, please call the MFN at 781-393-2106 from 4 p.m. on to find out about indoor arrangements for family concerts and events.
