Born in Portland, Oregon, she is one half of the famous musical duo of Bolcom and Morris. Her musical partner and husband is composer/pianistWilliam Bolcom. Together, they specialize in older popular songs, primarily from the first half of the 20th century, but extending beyond that to include both contemporary cabaret songs and a number of songs dating back to the American Civil War. In general, her performance practice is historically informed, rarely deviating from the original versions of songs for the sake of political correctness. Her singing voice is known for exceptional clarity, such that the lyrics are almost always completely intelligible. In early 2015 she announced that she and Bolcom would begin to curtail the length and number of their concerts, offering the next year as a sort of "Farewell Tour" after which they would limit performances to "cameo appearances."
