On Saturday night October 17, the Celtic supergroup Solas will transform the Lancaster High School Auditorium and Performing Arts Center in Irvington into a “mighty craic,” celebrating the spirit of Irish music. Widely acclaimed for their spellbinding musicianship and genre‑defying imagination, Solas—after three decades—remains one of the most influential ensembles in Celtic music today. The Boston Globe hails them as “the finest Celtic ensemble this country has ever produced.”
