New England-born, California-based composer John Adams is a pivotal figure in 20th century classical music, as he can be viewed as either the last of the Minimalists or the first of the Post-Minimalists. Though his music shares several traits with that of Steve Reich, Philip Glass or Terry Riley, Adams' music from his earliest works has used a wide variety of melodic, harmonic and rhythmic ideas, making his music perhaps more accessible to a new listener who might find works like Riley's "In C" or Glass's "Einstein on the Beach" too forbidding.
