Glassworks is Philip Glass's first studio album released by a major label, CBS Records, in 1982. It was designed to introduce his music to a wider audience, with shorter and more accessible pieces.
The album was recorded in New York between 1981 and 1982, and features performances by the Philip Glass Ensemble. The central piece, Opening, has become one of Glass's most famous compositions.
Glassworks marked a turning point in Glass's career, bringing minimalism to a mass audience. The work combines synthesizers, winds, and strings in a six-movement suite.
