Why Resonance Is Moving; and What’s Happening in September. For two fantastic years, Resonance Lough Derg has brought people together in Ballina/Killaloe to connect, share ideas, and experience something unlike anything else on the Irish festival calendar. A unique blend of intellectual exploration, artistic expression, and well-being; set against the stunning backdrop of Lough Derg. Fostering connections and inspiring new ideas, our aim is for the event to be immersive, intimate, and genuinely memorable.
