ArtBar at the Royal Sonesta in Cambridge is turning up the volume this season with a Summer Music Series featuring local acts performing on the outdoor patio. Come lounge by the river with local DJs performing every Thursday from 6:00pm to 10:00pm and live music every Friday from 6:00 to 9:00pm. There’s no cover, and ArtBar’s seasonal New American menu will be available to keep your energy up in case you feel like dancing. Check out the lineup here.
