Tennis -- "Marathon"

Tennis is a husband and wife duo originally from Denver who create catchy, lo-fi laced songs that, if not careful, could leave you staring at the sun for more than an hour. The duo came up with the name Tennis after wife Alaina Moore made fun of hubbie Patrick Riley's participation in tennis while in college. After escaping from their home in Denver, the duo traveled the North Atlantic coast on their boat; an experience that led them to write some of the most summer-y songs since John Stamos played bongos with the Beach Boys in Kokomo (he was also wearing a pink, tank top/belly shirt.)
