One of the most popular musical works during the Baroque era was Pergolesi’s plaintive Stabat Mater. It was so much in vogue during the middle of the 18th century that composers and their publishers would try to claim Pergolesi’s authorship of other spurious works. Performances of the Stabat Mater could be heard throughout Europe, even in France which maintained a superciliousness against Italian music. ABS will present the premiere of an edition found within the library of the Concert de Lyon, one of two trend-making concert organizations in France at that time. Also found within that library is Handel’s Utrecht Te Deum & Jubilate, triumphant music to celebrate the signing of the Treaty of Utrecht in 1713, eventually ending the War of the Spanish Succession.
