The Blues Drive-In returns for a third time to the Rockland Public Landing, 275 Main St., this Sunday, Sept. 6, from 4 to 5:30 p.m. with Tas Cru and his band, Tortured Souls.

“To make this work, there are some rules that must be followed,” said North Atlantic Blues Festival co-producer/founder Paul Benjamin.

Everyone will need to stay in their vehicles, he said, although those who come in pickup trucks may be in the truck bed with a mask on. To keep social distancing, every other parking spot will be used; cars also will be parked on the grass.

The event is free to the public, but a $20 donation per carload if possible is requested to help pay for the cost of the show. The public landing will be open during this time and anyone onsite is asked to wear a mask.

“I want to thank Rockland Harbormaster Matt Ripley and the City of Rockland for working with me on this. A special thanks goes out to First National Bank and the Hampton Inn as sponsors of these shows,” Benjamin added.
