Philip Glass

I was recently in the mood to expand my musical horizons, so I took a foray into modern classical music by checking out some Philip Glass from the library. While it is certainly very different than "classical" classical music, it really is excellent. He layers repetitive variations on particular rhythmic and tonal themes to generate some really interesting music. From a musical standpoint, it can be very minimalist, but that feature is what makes it compelling in my opinion. As a side note, because of its repetitive nature, it makes an excellent accompaniment to mathematics or physics problems.
