Last night fans flocked to the North Star Bar for a special concert in support of the victims of the Boston Marathon tragedy. Headliners Shorty Boy Boy put on an outrageous performance which involved building a tent in front of the stage to preform in; he also pulled a mid set outfit change into pajamas. Along with a killer light show, they made sure their set would not be soon forgotten by audience members. Indie rock band The National Rifle and poppy up-and-comers Cruiser also preformed.
