Making their way to the top of the venue chain are the Black Keys. They last played Boston in 2010 at a sold-out Bank of America Pavilion. The Arctic Monkeys themselves have climbed through the ranks and will play their first Boston arena show as the opening act. Is this a must see event for a pretty big Arctics fan? I’ve never seen a concert at the Garden and, in fact, have just one arena show to my credit — Bob Dylan & Elvis Costello at the Ryan Center in Rhode Island. It could very well be a first.
