Rachael Yamagata's forthcoming CD contains two parts. The first, Elephants, is the darker and more vulnerable of the two. It plays like a film score, with orchestral transitions that expand as the songs progress. The more guitar-driven Teeth Sinking Into Heart is grittier and more defiantly cynical. Underscored by Rachael’s husky alto and expressive piano (and now guitar) playing, the two parts, when taken together, present a snapshot of the emotions that revolve around heartbreak and the inevitable challenges of relationships
