Possessing an exquisite musicality rooted in modern-day folk, tuneful rock and countrified jangle pop plus a lyrical perspective brimming with real life and mature emotion, the two singer-songwriters known as Open Book have refined their distinctive sound with their sophomore CD release, The Things We Keep. Both Michele Rubin and Rick Gedney exhibit a gift for songwriting that entwines melody invention with astute observations of the heart backed by a tapestry of guitars. Their original compositions are filled with sharp hooks and sticky truths while adorning the whole with the kind of shimmering male-female harmonies rarely heard in today's music.
