Composer Steve Reich may be getting star treatment this year (he just turned 70,) but his music took a long time to be accepted in the concert hall. “The 1971 Boston Symphony performance of his ‘Four Organs’ — the first time his music had been played in a major concert venue — was cheered but also loudly booed in Symphony Hall. And when [Michael] Tilson Thomas performed the work in Carnegie Hall two years later, the audience proved even testier, erupting in protest in the middle of the performance.”
