INFLUENCES
Reich’s effect on musical culture is perhaps not as great as Philip Glass’s, although within classical circles his influence may be greater, owing to the modernist rigor of his music. Nonetheless, his characteristic pattering, marimba-and-winds sound has managed to spread further, appearing on pop remix albums
What does 'modernist rigor' signify here? Is Reich somehow more Minimalist than Glass?
