Lancaster’s The Stray Birds expand on the rich tradition of folk keeping the beloved genre alive and well. Maya de Vitry cut her teeth as a street performer while traveling across North America and Europe refining her songwriting skills. Classically-trained players Oliver Craven and Charles Joseph Muench assist in providing a sparkling web of instrumentation as a backdrop for Vitry’s charming vocals. The trio of multi-instrumentalists also has the ability to ignite the stage with down-home, Appalachian-style jams – old souls ready to influence and inspire a new generation. They’ll be headlining tonight upstairs at World Café Live with support from local Americana father-son duo Beaucoup Blue. World Café Live, 3025 Walnut St., 8pm, $8, All Ages – H.M. Kauffman
