More musicians are doing their part to help others!

Days after the Boston explosions, which killed three and injured over 200, Dropkick Murphys released t-shirts that read “For Boston” on the front and “Thank you, to all who purchase this shirt. All proceeds go to the victims and families of the Boston Marathon Bombings. Love, Dropkick Murphys” on the back. Within 15 hours, they’d raised over $65,000.

The band also played a benefit show at Boston’s House of Blues and released the Rose Tattoo: For Boston Charity EP, featuring Bruce Springsteen on a re-recording of their song “Rose Tattoo.”

“We were humbled by the kindness of our friends and fans who got behind this cause with so much heart and passion,” Band Member Ken Casey said in a statement. “It was truly an honor to be able to represent them and contribute, even if in a small way, to help these inspirational individuals.”

The bands’ efforts aren’t done. Continued sales of the EP and new shirts will bring more money to the victims, many of whom were visited by the band over the past few months.
