Belfast Summer Nights continues Thursday, July 30, from 5:30 to 7:30 p.m. at Steamboat Park, on the waterfront. Families are invited to bring dancing shoes, lawn seating and picnic suppers; no dogs are permitted in the concert area.

This week’s evening offers two groups that feature friends. Fretful Sam will play their original tunes written by the band mates — Wes Cotton, Julie Johnson, Scott Ryan and Leslie Stein. And Sean and Jamie Oshima and Alex Wilder will play folk, pop, soul and reggae as Mostly Brothers. Rain location is the Belfast Boathouse.

The series continues every Thursday night through August, with different artists and locations each week. For more information, call 322-7123 and check out the Facebook page.
