Chicago is lucky to still have a full-time classical-music radio station in WFMT, but for fans of composed music that’s less than a hundred years old, there aren’t so many opportunities to hear it outside of the concert hall or by purchasing recordings. There are occasions where something less musty gets on WFMT’s airwaves, as on host Seth Bousted’s weekly Relevant Tones program, but by and large the station doesn’t offer much proof that “classical” music is a living tradition. Today, however, the station is offering a refreshing antidote to convention with ten impressive hours of programming of truly contemporary music.
