While you are jammin’ in your lawn (or arena) seat listening to Jethro Tull on what would be an otherwise dull Sunday, please keep in mind what has really brought them to Jersey today. Tull is on tour to commemorate the sixty-fifth anniversary of Europe’s liberation after the second World War—yes really—and will be playing the PNC Bank Arts Center on June 13. Also performing is special guest Procol Harum. (8 p.m. Tickets from $25.25 – $85.25; WW2 Veterans’ discount unclear at press time.)
