The family-fiendly Cake for Dinner, featuring members of Celtic group Scythian, will kick off Strathmore’s Free Summer Outdoor Concert Series on Wednesday, June 20. The quartet introduces young musicians to the basics of music — melody, harmony and rhythm — through a sampling of global folk music from Italy, Ukraine, Ireland and Argentina, as well as French Canadian tunes and Appalachian bluegrass. Written by Alexander and Danylo Fedoryka for their 25 nephews and nieces, the self-titled album is a sonic trip around the globe. Alexander and Danylo also perform in the multiform world of ethnic music with their band Scythian, with which they currently tour. All performances are at 7 p.m. on Wednesday nights at the Gudelsky Concert Gazebo, in front of the historic Mansion. For a complete listing, visit www.strathmore.org.
