Dual is an album by four acclaimed Irish and Scottish musicians: Éamon Doorley, Muireann Nic Amhlaoibh (both prominently of Danú), Julie Fowlis and Ross Martin.

The album was planned to project the similarities and differences between the Irish and Scottish Gaelic song traditions.

Julie and Muireann have had very similar upbringings and found their music and languages shared many common threads.

Hence the name, Dual, which means "to braid, to twine, inheritance or native" in both Irish and Scottish Gaelic.

The album features songs in Irish and Scottish Gaelic, and tunes from both cultures.
