Some songs you enjoy in the background while others take up residence in your bones. Sam Phillips’ music is in the latter category. She was Christian pop artist Leslie Phillips until she outgrew those constraints and, as Sam, began releasing such transcendent songs as “Holding On to the Earth” and “I Need Love” and wonderful albums such as the spirited The Indescribable Wow, the tour de force Martinis and Bikinis and the intimate Fan Dance. What threat did she make to get released from her Christian label? How did she wind up playing a mute villain in Die Hard with a Vengeance? How is she still searching for the euphoric? She’s as perceptive and spellbinding in conversation as in song.
