O Quam Tristis is a reflective Lenten concert inviting listeners into a profound musical meditation on sorrow, sacrifice, and hope. Through a carefully curated programme inspired by the Passion and the themes of Lent, the ensemble uses the warm, solemn sonorities of brass to evoke deep emotion and spiritual contemplation. Now in its fourth edition, this concert continues to offer a meaningful artistic experience that encourages silence, introspection, and prayer through music.
