Philip Glass is an American composer. His music is considered to be minimal music, although he himself uses the term theatre music.

Glassworks was originally released in 1982. The album is a six-part chamber music work by Philip Glass. After his larger-scale concert and stage works, Glassworks was Philip Glass's successful attempt to create a more pop-oriented “Walkman-appropriate” work, with significantly shorter and more accessible pieces written for the recording studio. In fact, the cover of the cassette release stated that it was “mixed especially for your personal cassette player”.

Glassworks 40th anniversary edition is pressed on crystal clear vinyl.
