Be/Non frontman/mad scientist Brodie Rush has been making some of the most adventurous, experimental space rock in the Midwest since the late '90s. But his latest opus, A Mountain of Yeses, is his most conceptual work to date. Its songs focus on the journey of a post-apocalyptic space traveler. While searching for a suitable planet on which to live, he ends up on an abstract, intergalactic journey toward self-actualization. The music that accompanies this otherworldly tale is just as quirky: Metronomic synthesizer and drum patterns lay a foundation for classic prog that's then filtered through the past 30 years of musical devolution and advances in technology. It's an eerie combination that does a great job of capturing both the propulsive energy of space travel and the true, cold loneliness that would accompany a solo voyage through foreign galaxies.
