Having earned his composing stripes after the 1960s, John Adams had the pioneering work of Steve Reich, Philip Glass, and Terry Riley close at hand as he ventured into his trade. And, while minimalism's historical continuum helps place Adams, he used Reich, Glass, and Riley (among others) only as a starting point. And here's proof: a 10-CD retrospective of nearly all Adams's recorded compositions on Nonesuch Records, the label that also issued and . Adams's , a choral work of startling energy and effervescence, appears here in a new recording, as do distillations of both and , two path-clearing operas. Over the span of a career covered by , Adams has returned minimalism to traditional instrumental ensembles as well as to projects that at once advanced a political commentary and took that commentary back to orchestral audiences. And so, in far less time than his predecessors, Adams created works that now play like standard repertoire pieces: and and the Violin Concerto--all of them are here. What these works demonstrate is a fierce creativity on the one hand and perhaps a hunger for commercial advances on the other. Adams may at times be a bustling free thinker, but he sounds ever conscious of what audiences are listening to. As for the works themselves, they remain every bit as daunting as when written. Some may object to particular selections. , for example, hardly ranks with Adams's best work. But this box isn't a mere best-of; it's an almost-all-of. At times terrifically American--especially in the news-aware operas and their narrative pragmatism--Adams well deserves a major box set, and its coverage is appropriate to his varied, stylistically diverse output. As with any large-scale retrospective, --which fairly bristles with Adams's new composition, --has spots where fans might balk at the quality of the composer's writing. But it's got a fantastic accompanying booklet along with its many hours of inarguably modern and thoroughly listener-friendly music.
