Sisters Natalie (cello) and Brittany Haas (fiddle) began their musical lives together, filling their childhood home with Bach suites and Old-Time tunes alike. It was on their own, however-following divergent paths through disparate musical traditions, countries, and cultures-that they both arrived as virtuosi and composers at the highest levels of contemporary string music. Fans of acoustic music can hardly mention one without referencing the other's work. With HAAS, these singular musicians finally record together - in duo form - for the first time. It is a collaboration a lifetime in the making, and a music encompassing travels through time and through the world. From Nashville to Norway, the Celtic Isles to California, Natalie and Brittany have absorbed, adapted, and made their own world of music. The result? HAAS.
