Classical Celtic pop.Folk-oriented, classical music with a Gaelic flavor as strong as a whiff of stout from a Dublin pub.

These are a few of the ways the unusual sound of the artsy quartet Nightnoise has been described.

Whatever you call it, the group has succeeded in creating a distinct style that has been inspiring standing ovations on recent international and national tours.

Nightnoise will perform with two other Windham Hill artists - pianists Liz Story and Philip Aaberg - in the Winter Solstice Concert at Kingsbury Hall, Saturday, Dec. 15, at 8 p.m.

The show celebrates the advent of the winter season and the release of the "A Winter's Solstice III" album, showcasing the artists in solo, duet and ensemble performances.

Three members of Nightnoise are natives of Ireland - guitarist Micheal O'Domhnaill, keyboardist Triona Ni Dhomnaill and flutist Brian Drunning. Violinist Bill Oskay is the only American in the band. The traditional folk music plays a vital role in the group's synthesis of folk and jazz - with classical and rock 'n' roll influences.

In an interview from Nashville, Ni Dhomnaill said she's thrilled with the enthusiastic reception the "Solstice" tour has been receiving.

A New York Times critic referred to her as "one of the glories of current Irish folk music."

Vocal tradition runs deep in her family. "We were surrounded by music when we were kids and listened to everything from Ella Fitzgerald and the big bands to classical music - and, of course, the Beatles, the Stones, Bob Dylan and Joan Boark as well as the entire British contingent of folkies."

Critics describe her vocals as "haunting and delightful."

Dhomnaill composes songs, drawing upon her rich musical background and "things I see and feel everyday that hopefully strike a chord in others."

She was inspired to write the carol "Snow is Lightly Falling," which will be featured in the Salt Lake concert, while on tour in Japan.

"I was lonely and ready to go home. To find comfort, I imagined being in the midst of a beautiful snow-filled forest. The words just came. The next day I put it to music."

Story is a pianist whose music is a whimsical, engaging, thoughtful blend of classical, jazz and folk. Critics refer to her as a storyteller, a soulful pianist who has a graceful command of the keyboard, creating moving music.

Aaberg is noted for his rigorous technique and broad musical perspective - from classical to pop and rock.

Defining himself musically, Aaberg says, "I'm combining an authentic sense and front-line experience of American traditional roots and rock and roll music with a new music aesthetic and vocabulary - a genuine sense of form and structure.

"I'm sorry. It can't be defined in two words."
