In the early 1990s, Siggy toured internationally as a featured vocalist with “Broadway Musicals New York”, which played in fourteen countries. While on tour in Berlin, she met Queen Yahna and Januari Watts, who subsequently introduced her to the international music and theater scene. Siggy “cut her Jazz teeth” at Gary Wiggins Blues Cafe in Berlin working with Reggie Moore, Earl Bostick, and Eb Davis, to mention but a few. She was also invited as a house artist at the historic Tränenpalast, where she was showcased by Marcos Herold for fourteen years, garnering such honors as invitations to perform for President Bill Clinton and receiving a painting of herself on the former Berlin Wall.
Siggy has headlined in Europe with such artists as James Carter, Archie Shepp, Nina Hagen, Kim Clark, Omar Sosa, Charlie Mariano, Mari Ann Larsen, and Joe Bowie, just to name a few. Always keeping her foot planted in the theater, Siggy has been featured in productions at the Theater des Westens, Hamburg Schauspielhaus, Theater am Gartnerplatz, and the Deutsche Oper. She has starred as Effie in Dreamgirls, Sonya in The Life, Ella Fitzgerald in Marilyn, and sang Tina Turner / Janis Joplin in the international company in Beehive.
