From childhood tunes to chambergrass mastery.

Natalie and Brittany Haas spent their childhood trading Bach suites and Old-Time tunes in equal measure. Then they went their separate ways and became two of the most influential string players working today.
Natalie put cello on the map of contemporary Celtic music through her duo with Scottish fiddler Alasdair Fraser, absorbing influences from across continents and fashioning a rhythmic approach that belongs to no single tradition. Brittany's fiddle work with Punch Brothers, Hawktail, Crooked Still, and Dave Rawlings Machine has redefined what's possible in American acoustic music, crossing genres with an approach that feels both ancient and entirely new.
Reuniting as HAAS, the duo presents chambergrass music that refuses categorisation. From Nashville to Norway, the Celtic Isles to California, they've built a shared musical vocabulary that moves fluidly between melodic hooks, call-and-response, accompaniment and lead.
With their effortless, intuitive interplay, and having spent decades mastering both their craft and the art of listening to each other, watch as the power of seeing siblings reunite takes centre stage.
