Concerto Polacco was formed in 1991 by Marek Toporowski, a renowned Polish harpsichord and organ player. Starting initially as a small chamber music ensemble, Concerto Polacco soon became a real baroque orchestra performing with period instruments. Sine Nomine chamber choir was founded by Marek Toporowski in 1996. Its repertoire consists of renaissance, baroque, classical and romantic music. Together Concerto Polacco and Sine Nomine form the first Polish early music ensemble consisting of a chamber choir and an orchestra playing on period instruments. The principal aim of both ensembles and their artistic director, Marek Toporowski, is to present the greatest masterpieces of vocal and instrumental music with the main emphasis on 17th- and 18th-century music. In 1998 they began a series of concerts titled “Masterpieces of Oratorium and Cantata Music”. Within this series the groups presented St John’s Passion, Mass in B minor and many cantatas by JS Bach, Chandos Anthems by GF Handel and other masterpieces. In addition they perform Polish baroque and classical music. Performed with period instruments, the music from the times of Polish prosperity and splendor becomes vivid and alive, highlightening Polish participation in the European culture.
