Over the years, artists have likened themselves to countless inanimate objects as a way of saying “take me, I’m yours” — vacuum cleaners and Ford Cortinas come to mind — and S AND R just added balloons to the heap. The Boston duo of Saxon Kennedy and Reeve Pope drift into the realm of indie-pop with “Party Balloon,” their new single and first release since their May EP Honey, Look At My Face. The tune arrived earlier this month (December 6), funneling the lightheaded joy of devotion into an offer to float through life with someone. “Party Balloon” is a promise of levity, bobbing towards the group’s upcoming February EP. Join the festivities below.
