Natalie is one of the most sought after cellists playing traditional music today. She and Scottish fiddler Alasdair Fraser have toured as a duo for over twenty three years, wowing audiences at festivals and concerts worldwide with their unique sound. Their first album together, Fire & Grace, was awarded Best Album of the Year in the Scots Trad Music Awards 2004. Natalie has also toured with Mark O'Connor as a member of his Appalachia Waltz Trio. She and O'Connor premiered his double concerto for violin and cello, ¨For The Heroes¨, with the Grand Rapids, East Texas, and San Diego Symphonies. As a studio musician, Natalie has been a guest artist on over 100 albums, including those of Cape Breton fiddler Natalie MacMaster, Irish greats Altan, Solas, and Liz Carroll, and Americana icon Dirk Powell. 

A graduate of the Juilliard School, where she studied with cellist Fred Sherry, Natalie discovered the cello at age nine. In addition to having extensive classical music training, she is accomplished in a broad array of fiddle genres. Her music journey found purpose when she fell in love with Celtic music at the Valley of the Moon Scottish Fiddling School at age 11. Inspired and encouraged by director Fraser, she began to investigate the cello's potential for rhythmic accompaniment to fiddle tunes, and to this day, the two continue to resurrect and reinvent the cello's historic role in Scottish music.

Natalie's skills as an educator make her one of the most in demand teachers at fiddle camps across the globe. She also teaches privately and in a workshop setting.

¨Natalie basically wrote the book on the cello's place in Celtic music.¨ - Peter Winter

¨In the hands of Natalie Haas, the cello becomes a truly magical instrument." - Green Man

"You would think they'd been playing together for centuries. While his fiddle dances, her cello throbs darkly or plucks puckishly. Then she opens her cello's throat, joining Fraser in soaring sustains, windswept refrains, and sudden, jazzy explosions. Their sound is as urbane as a Manhattan midnight, and as wild as a Clackmannan winter." - Scott Alarik

¨[Alasdair and Natalie] create a sumptuous orchestral mix through the subtle art of aural implication, an intricately textured sound built upon Haas’s extended cello technique." - Andrew Gilbert
