Metallica has made it a point to raise awareness and funds for area food banks when on tour.  The group is also asking fans to step up and volunteer at food banks.  A concentrated campaign is underway to mobilize as many as possible on May 23. The Metallica Day of Service is being coordinated by the group's foundation, All Within My Hands.  Fans that register online to volunteer at food banks in a number of cities will be thanked by the band with a limited edition t-shirt.
