In 2009, the married couple Patrick Riley and Alaina Moore bought a 30-foot sailboat named the Cape Dory after six years of scrimping and saving. The pair – who are from Denver — had no sailing experience, but equipped with a copy of The Annapolis Book of Seamanship, they spent eight months journeying up the Eastern Seaboard, from the Bahamas to Baltimore. Upon their return, they wrote a record about it. The Marathon EP features sweet songs inspired by Wall of Sound girl groups like the Shirelles, with fuzzed-out layers of simple keys and guitar and Moore’s lively, sophisticated vocals. Come January, Tennis will release their first full-length, Cape Dory, containing even more delightfully radiant songs with titles like “South Carolina,” “Bimini Bay,” and “Seafarer.” With The Golden Blondes.
