The relationship between classical and electronic music dates as far back as the ’30s, when composers started weaving then-new instruments like the ondes martenot into the fabric of the orchestra. It didn’t just broaden music’s sonic palette, but also the ways in which music could be composed—ideas that were further explored by experimental composers such as Philip Glass and Steve Reich in the ’60s. Since then, the boundary between classical and electronic has become fully porous, giving rise to a style of composition that bridges electro and acoustic, tradition and possibility. These pieces, which we refresh regularly, offer a cross section of where we are now. If you like something you hear, add it to your library.
