Two leaders of the new generation of very talented Irish musicians — pipe and flute player Louise Mulcahy and fiddler Oisin Mac Diarmada — perform a concert of traditional music at 8 p.m. on Saturday, Nov. 3, to finish off this year’s outstanding Irish music series at Katharine Cornell Theatre on Spring street in Vineyard Haven.

This spectacular pairing of two All-Ireland Champions promises energy and creativity in their playing combined with a true love and respect for the tradition.

Oisin Mac Diarmada has been a favorite of Island audiences attending the KCT Concerts series for the past few years. His first performance here was in 2001 with the newly formed band Teada — it was the very first concert the band performed in the United States. With Mr. Mac Diarmada as the leader, organizer and creative force, they went on to become one of Ireland’s most successful bands, playing all over the world and touring nearly non-stop. This concert will be his sixth performance here.

His band’s most recent recording, InnéAmárach (or Yesterday Tomorrow), was the only Irish entrant in Mojo’s top 10 albums of 2006. About his solo album, Ar An BhFidil, Hot Press in Dublin said, “It does exactly what it says — pure traditional fiddling, raw and unadorned and all the better for it.”

Louise Mulcahy is the leading female uilleann piper in Ireland as well as a powerful flute and whistle player. At the age of 16 she was invited to teach tin whistle and flute at the famous Willie Clancy Summer School in Miltown Malbay, Ireland. At the same festival she was asked to play in the Piper’s Concert; there had never been a woman piper on the stage there before.

In 2000 Ms. Mulcahy collaborated with her father Mick and sister Michelle on The Mulcahy Family, which finished in the Irish Echo’s top 15 traditional albums for that year. Their new disc, Notes From the Heart made the Irish Echo’s number five spot for best albums. She shared the 2006 Live Ireland Award for female musician of the year with her sister.
