PORTLAND — Two Boston acoustic musicians, Irish flutist Shannon Heaton and Celtic harpist Maeve Gilchrist, will get together Saturday, Feb. 5, at The Empire Dine and Dance.

They will celebrate the release of Heaton’s new all-instrumental CD, “The Blue Dress,” featuring Gilchrist on harp, Paddy League on bodhran and bouzouki, and Matt Heaton and Liz Simmons on guitar.

A member of the Boston Celtic music scene for almost a decade, Heaton often appears with her husband, Matt, with whom she tours nationally and abroad.

Gilchirst, a native of Scotland, is a sought-after advanced harp instructor. She expects to soon release her second album, produced by virtuoso fiddler Darol Anger.

Tickets to the 8 p.m. show are $15 in advance. They are available at Bull Moose music stores and at www.mktix.com/heptunes.
