A full day and evening of Celtic music is in store at the annual Summer BCMFest, which takes place July 2 at Club Passim in Harvard Square.

This year’s festival includes free outdoor concerts and participatory ceilidh outside Passim in Palmer Street, and a ticketed evening performance in the club.

The event is tailored after the winter BCMFest (Boston Celtic Music Fest), held each January to celebrate Greater Boston ’s richness of music, song, and dance from the Irish, Scottish, Cape Breton, and other Celtic traditions. Like its winter counterpart, Summer BCMFest showcases the diversity of sounds and styles found in Boston’s Celtic music community.
This edition of the festival will begin with a “Live Music Brunch” from 10 a.m. to 2 p.m. featuring an Irish music and song session led by Kat Wallace and Jimmy Kelly.

At 3 p.m., the Palmer Street outdoor show kicks off with an Irish/roots music set from multi-instrumentalist Elias Cardoso and friends. They will be followed by Ailsa McFadyn & The Ginger Ales, who will perform songs from Irish, Scottish and other traditions.

BCMFest’s popular Boston Urban Ceilidh dance event will run from 5 p.m. to 6 pm. The “Ceilidh in the Alley” will encompass social dances from Ireland, Scotland, and Cape Breton and will be open to all regardless of experience level. Summer McCall will call the dances, with a Boston Urban Ceilidh band of Elizabeth Anderson and Leland Martin (fiddle), Adam Hendey (guitar), and Rachel Reeds (piano).

Summer BCMFest shifts indoors to Club Passim for a 7 p.m. to 9 p.m. concert of Irish music with Matt and Shannon Heaton, Scottish tunes played by the Carroll Sisters with Adam Hendey, and the Quebecois duo of Yann Falquet and Eric Boodman.
