Unity College Centre for the Performing Arts, 42 Depot St., will present Alasdair Frazer and Natalie Haas Thursday, April 7 at 7:30 p.m. The award-winning duo will unleash their dazzling teamwork, driving, dancing rhythms and shared passion for taking the infectious melodies and grooves of Scottish/Celtic music on an exciting new journey.

The musical partnership between Fraser, long regarded as Scotland’s premier fiddle ambassador; and the sizzling-talented young California cellist Haas may not seem an obvious one. Fraser has a concert and recording career spanning 30 years with a long list of awards, accolades, television credits, and feature performances on top movie soundtracks. Fraser has been sponsored by the British Council to represent Scotland’s music internationally; and received the Scottish Heritage Center Service Award for outstanding contributions to Scottish culture and traditions.

The 25-year-old Haas, a graduate of the Juilliard School of Music, was not even born when Fraser was winning national fiddle competitions on the other side of the Atlantic. But this seemingly unlikely pairing is the fulfillment of a long-standing musical dream for Fraser, whose cutting-edge musical explorations took him full circle to find a cellist who could help him return the cello to its historical role at the rhythmic heart of Scottish dance music.

Haas was just 11 when she first attended Fraser’s Valley of the Moon Scottish Fiddling School in California. She responded to Fraser’s challenge to find and release the cello’s rhythmic soul and, four years later, when she was just 15, Fraser and Haas played their first gig together. Now regularly touring with Fraser and creating a buzz at festivals and in concert halls throughout Europe and North America, Haas is in the vanguard of young cellists who are re-defining the role of the cello in traditional music.

The duo has performed frequently in Europe and throughout the United States and Canada. They have been featured on National Public Radio’s “Performance Today,” “The Thistle & Shamrock” and “Mountain Stage”; and represented Scotland at the Smithsonian Museum’s Folklife Festival. In addition, Fraser and Haas have busy teaching schedules including summer fiddle courses in the U.S., Scotland and Spain. Haas also teaches at the Berklee College of Music in Boston.

Tickets are $20. Next up at Unity College Centre will be premier old-time fiddler Bruce Molsky Monday, April 11 at 7:30 p.m. ($15). For more information, call 948-7469 or visit unityme.org.
