Humans have always looked to the sky for answers to the big “Why?” And composers have done the same. The Houston Chamber Choir offers a stellar compilation of pieces that ponder the heavens. The centerpiece of this program, in addition to music by Heinrich Schütz, Venezuelan-Texan Carlos Cordero, Johannes Brahms, and others, is the breathtaking “Consolation of Apollo.” Written in 2014 by American composer Kile Smith, “Consolation” has important connections to Houston, with texts pulled from the philosopher, Boethius, as well as from the astronaut crew of Apollo 8. Accompanied by breathtaking projections of images from and about space, this concert is sure to engage the imagination aurally and visually.
