Emerging in the early 1980s as a grassroots cooperative of musicians, Portland Baroque Orchestra (PBO) is considered one of the best period-instrument orchestras in North America and Europe. PBO’s mission is to produce intimate and historically-informed interpretations of music composed before 1840 for a wide audience, and to provide broad access and educate the community about the composers and historic context of this music through world-class professional performances, outreach and dialogue.
