The contemporary classical genre called Minimalism arrived in the middle of the 20th century as a reaction against the rigid avant-garde theories of Serialism, which threw out the tonal center and harmonic systems of a thousand years of European music. Serialism was intellectually brilliant—unfortunately, the music was ugly, tedious, and unpopular. In the 1960s, a number of American composers including LA MONTE YOUNG, TERRY RILEY, STEVE REICH, and PHILIP GLASS found their way back to tonality, with a style based on "minimal" elements: consonant harmony, static drones or a steady pulse, and slowly changing thematic motifs.

The piece has been a phenomenon in the Netherlands for 40 years and hundreds of sold out...
