Maxwell believes deeply in the importance of cultural diplomacy and frequently performs overseas, headlining sold out concerts in Italy, France, Japan and China, and performing at the United Nations 67th annual Commission on the Status of Women.  She recently made her Lincoln Center debut as a soloist in David Geffen Hall, singing in both Mandarin and in English to standing ovations. She then made her China performance debut with concerts in Beijing and Shanghai, including at the US Embassy in Beijing. Maxwell frequently performs in Japan as a headliner with Classical Music Collection Japan, including a sold-out performance at Nishi Hongwanji Temple, the first performance ever allowed at the UNESCO World Heritage Site. 

Maxwell has a chameleon-like voice, with both a bright coloratura and a rich and powerful lower register.  She performs classics from Leonard Bernstein’s “Glitter and Be Gay” to Harold Arlen’s “Stormy Weather”.  She sings opera, Broadway, pop, jazz, country, bluegrass and sacred music.
