Lyambiko is a pseudonym of German singer Sandy Müller and the name of a band she fronts, with USA's Marque Lowenthal (piano), Canadian Robin Draganic (bass) and German Torsten Zwingenberger (percussion).

A trio of Lowenthal, Draganic and Zwingenberger had been playing together for several years when they found Müller.

Müller, born in Thüringen to an amateur musician from Tanzania and a German mother, had begun to sing jazz only a year before the trio was formed. Now she takes the stage with her new accompanists and fascinates audiences with her own unique sound.

By the end of 2004 Müller had given approximately 300 concerts with her trio, the majority of those in Germany and three in the United States, where she enjoyed great successes in New York and Boston and was likewise acclaimed by the American press. She also appeared in France, Austria, Switzerland, Poland and the Czech Republic and is set to perform in other countries in 2005.
