Editor’s Note: By the third day of a music festival, you’re running purely on adrenaline. Add in subpar weather (a classic New England springtime mix of rain, cold, and wind) and it falls on the bands and artists on stage to keep spirits high. Luckily, that’s what happened Sunday (May 27) for Boston Calling’s third and final day at the Harvard Athletic Complex. The Green Stage was hot mix of styles, led by hip-hop legends Eminem and Beastie Boy Mike D, as well as Los Angeles multi-instrumentalist Thundercat, Australian psych band Pond, and New England alt-rock trio Weakened Friends. Matthew Shelter was up front for it all, and you can scan through his full Sunday gallery from the Green Stage, in reverse order of appearance, below.
