After a brief career in molecular genetics, vocalist and lyricist Stephanie K. (Klco-Brosius) relocated to Germany with her growing family in1995.
She performs diverse styles of music ranging from blues to the American songbook, with ensembles from duo to big band. 
Stephanie has performed in many international festivals, notably an opening act for trumpeter Randy Brecker, and private celebrations including functions and clubs in Europe, the US and Tunisia.
Stephanie concentrates on expanding and enriching her repertoire by cooperating with musicians both in Europe and the US to form duo to extended combo situations supporting her interpretations of standards, torch songs and ever more prominent, her own originals.
“Going Vocal” ( 2002) a project with big band was the first of four recordings under the MUSICOM, Germany label. A live recording supported by jazz combo, "Do Something" followed in 2003, "Subterranean Dream" (2007), a mix of standards, pop tunes and Stephanie K. originals, was recorded in 2007 in NYC and co-produced by pianist Aaron Goldberg and bassist Reuben Rogers.
Stephanie K has emerged like the Venus of jazz – with a fully-developed style that is more in keeping with that of a veteran artist. 
Her voice has a presence that immediately captures your attention, drawing you into her sphere of musical influence, emitting flashes of Aretha Franklin, Carol King, Diana Krall and Billie Holiday.
Yet Stephanie K is no derivative jazz singer; she is a true original.
She has at her command an impressive level of musicianship, with the phrasing, intonation and time sense of the seasoned jazz musician.
That she came by all this as a mother of four living in Northern Germany for the past sixteen years is powerful testament to her natural abilities.
Stephanie K’s musical tastes run to rich, rarely-heard ballads that are brought to life by her torchy vocal style, fresh renderings of canonical popular tunes and vivid transformations of chestnuts from the American songbook. 
Her latest release, "In the Silence of the Snowfall" 2010 is a cocktail of winter songs, holiday evergreens and contemporary originals: one written by Patricia Barber and the last and title track written by Stephanie K herself.
The CD was recorded in Germany, featuring custom arrangements for Stephanie written by bassist/composer/arranger Jürgen Knautz for string quartet and jazz ensemble.
28 October 2011 new single release "Don't Friend Me On Facebook".
