Tyson Ritter and his band All-American Rejects performed at the first of two Mix 104.1 “Not So Silent Night” concerts at the Lansdowne Pub on Saturday night. Ritter (center) reported on Twitter that he enjoyed a lobster roll at Neptune Oyster during his visit. “Merry Christmas to me!” he tweeted. Vermont’s Grace Potter and the Irish band the Script were also on the bill. Friday’s second “Not So Silent” show will feature Neon Trees and Phillip Phillips.
