Cecilie Grundt (13th of July 1991) was born and raised in Stavanger, Norway. Her family enjoyed listening to both classical and jazz music from their record collection from an early age, exposing her to music of Dexter Gordon and Charlie Parker. No wonder she began playing alto saxophone at age nine. She began taking lessons at the Stavanger Performing Arts School, while in the meantime she played in different marching bands, where she often performed as a soloist.
Cecilie was playing both the alto and soprano saxophone at age 14, before the tenor became her obsession at age 16. She listened more carefully to numerous jazz recordings, and played along with them. She cites John Coltrane, Sonny Rollins and Jan Garbarek as her main influences at that time.
