What Clint and Grace McCune, also known as the band Twirl, have aspired to since coming to Orcas is to playing at the Orcas Center.

“Ten years ago we said, ‘Someday we will play on the Main Stage of the Orcas Center’ and now it’s happening,” Grace said. “This concert has a significance for us to where we have come as musicians.”

Their musical past has included: the Stage on the Green, the Odd Fellows Hall, numerous venues in Seattle, the South by Southwest Festival, all over the East Coast and the South, MTV, and headlining for the North Carolina Music Festival to an audience of 5,000. But it’s the Orcas Center’s Main Stage that has been their dream, and on May 9, for one performance only, that’s where they will be.

“Our voices are unique and we do a lot of harmonizing. Since we are related, there is a similar tenor to our voices. We twirl together the masculine and feminine versions to create a unique sound,” Grace said.

Performing is in the family. Their father, Don McCune, was a television personality on KOMO for many years. He was the kid’s favorite “Captain Puget,” and then had a documentary series “Exploration Northwest.” Their mother was the band director at a local junior high.

“We call my brother, the banker, the black sheep in the family,” Grace laughs. “I was playing the piano by the time I was three years old. Clint was drawn to the guitar. There is a photo of us when my brother is three years old and I am about one. He is playing a tennis racket like it’s a guitar and I am banging on my stroller as if it were a piano.”

In 2000, both were performing independently. Clint traveling by sailboat from port-to-port and Grace in her trailer journeying by land. On a phone call, they first talked about performing together.

“I will never forget our first gig together,” Grace said. “We were walking around trying to find a place to play, and a band had just cancelled at a local bar. With 30-minutes before we were on stage, we each took a bar napkin and wrote down our songs and cords, we switched napkins and said, ‘let’s go play.’ It was great.

“MTV was recording a commercial for the bar, we were there and were featured. We said, ‘Wow! Our first week and we’re on MTV.’ It was just happenstance, but by the end of the summer we had become very popular,” she said.

Clint, who now lives in Redmond, founded a music venue, SoulFood, and serves as a Redmond Arts Commissioner.

“I spent a lot of years living on Orcas as part of the tribe. We know the island is magical and we plan to provide a magical night of music in celebration,” Clint said. “Our music changes daily and we never play the same song, the same way, twice. Growth and change are the most exciting part about music,” he said. “To be in a band with a family member you can go places without having to talk about it. You instinctually know where to go. This keeps the moment of now limitless.”

Grace is a multi-talented performer who has appeared on Orcas stages, in a variety of roles including “Steel Magnolias,” “Three Penny Opera,” and “Beauty and the Beast.” She was a guest soloist for the “One World Music Festival” and with Orcas A Capella.

Wayne Horvitz and Robin Holcomb, the husband and wife musical team, will also be featured at the Orcas Center as part of the same musical evening.

Both have a multi-faceted career independently and often collaborate on projects. Each is a composer and pianist, and Holcomb is a singer and songwriter. They have performed extensively in Europe, Asia, Australia, and North America with an impressive list of artists including John Zorn, Fred Frith, Julian Priester, Bill Frisell and Peggy Lee.
