Matt Maher's intense, introspective songs come off like personal prayers. The Catholic singer/songwriter's rich, pleading voice seemingly rises from the depths of his soul on worship hits like 2008's “Your Grace Is Enough.” A multi-instrumentalist with a degree in jazz piano, Maher uses stellar musicianship to create warm, supple textures that listeners can sink into in times of spiritual need: Worship doesn't get any more inviting than his gospel-flavored “Hold Us Together” and the soaring rocker “Just as I Am.”
