The wont of popular music performers to produce seasonal material celebrating the Christmas season is a tradition reaching back several decades and, typically, works as a ploy to print money by preying on people’s sentiments. Some offerings strike us as self-consciously crafted confections playing on popular tropes, but there are some efforts that come along each year notable for their musical creativity and unbridled honesty. Kelly McGrath’s latest single “O Holy Night” joins the ranks of the latter thanks to its pure-hearted theatricality that highlights the scale of McGrath’s vocal talents and the wise arrangement she chooses to move this tune along. Rather than tossing a bunch of needless musical tinsel onto the recording, McGrath chooses to take a much more minimalist approach certain to connect with audiences and the sparse musical accompaniment adorning the song is expertly applied and doesn’t betray even a hint of self-indulgence.
