A crowded weekend offers the last opportunity to catch the Wexford Festival's pair of enterprising choral concerts, Martinu, Bruckner and Brahms at St Iberius Chureh this morning, and Durufle and Stravinsky tomorrow afternoon at Rowe Street Church. The Bach Festival of Ireland's period-instruments orchestra, Christ Church Baroque, spreads its five concerts over a week, starting with motets and organ works tomorrow at 5.30pm (with the Choir of Christ Church Cathedral under Mark Duley, and Malcolm Proud on Christ Church Cathedral's Kenneth Jones organ), and later running to the Art of Fugue Colm Carey, on Tuesday), multiple harpsichord concertos (Thursday), and Brandenburg Concertos and cantatas (next Saturday and Sunday).
