Sergei Mikhailovich Nakariakov (Russian: Сергей Михайлович Накаряков; born May 10, 1977 in Gorky) is a Russian virtuoso trumpeter who came to prominence in the late 1990s. He released his first CD recording (including works by Ravel, Gershwin and Arban's The Carnival of Venice) in 1992 at the age of 15.

Sergei Nakariakov has recorded works by composers such as Joseph Haydn, Johann Nepomuk Hummel, J. B. Neruda, Mozart, Telemann, Felix Mendelssohn, and Tchaikovsky. He has recorded with The Saint Paul Chamber Orchestra conducted by Hugh Wolff, and the Philharmonia conducted by Vladimir Ashkenazy among many others. In 2004 he was portrayed in Jan Schmidt-Garre's film No More Wunderkind.

Nakariakov's recordings include:

Nakariakov also has made several recordings performing on the flugelhorn. In his album Concertos for Trumpet in 1999, Nakariakov plays music transcribed for the trumpet from violin, viola, and cello concertos. He plays the flugelhorn for the famous Cello Concerto No. 1 by Haydn. In his album No Limit in 2000, Nakariakov plays Tchaikovsky's Variations on a Rococo Theme, originally for cello and orchestra, in a transcription for the flugelhorn. Nakariakov plays on a specially customized flugelhorn made by Antoine Courtois that has 4 valves, which allows him to play lower than normal flugelhorns.

Domenico Cimarosa (17 December 1749, Aversa, Province of Caserta – 11 January 1801, Venice) was an Italian opera composer of the Neapolitan school. He wrote more than eighty operas during his lifetime, including his masterpiece, Il matrimonio segreto (1792).

Cimarosa was born in Aversa in Campania.

His parents were poor, but, anxious to give their son a good education, they sent him to a free school connected with one of the monasteries in Naples after moving to that city. The organist of the monastery, Padre Polcano, was struck by the boy's intellect, and voluntarily instructed him in the elements of music and also in the ancient and modern literature of his country. Because of his influence, Cimarosa obtained a scholarship at the musical institute of Santa Maria di Loreto in Naples, where he remained for eleven years, chiefly studying with great masters of the old Italian school; Niccoló Piccinni, Antonio Maria Gaspare Sacchini, and other musicians of repute are mentioned among his teachers.

Ton Koopman (born 2 October 1944 in Zwolle, Netherlands) is a conductor, organist and harpsichordist.

Koopman had a "classical education" and then studied the organ (with Simon C. Jansen), harpsichord (with Gustav Leonhardt) and musicology in Amsterdam. He specialized in Baroque music and received the Prix d'Excellence for both organ and harpsichord.

In 1979 Koopman founded the Amsterdam Baroque Orchestra and the Amsterdam Baroque Choir in 1992 (now combined as the Amsterdam Baroque Orchestra & Choir). Koopman concentrates on Baroque music, especially that of Bach, and is a leading figure in the authentic performance movement. While a number of early-music conductors have ventured into newer music, Koopman has not. He has said, "I draw the line at Mozart’s death" (1791). One exception is his recording of the Concert Champêtre of Francis Poulenc, written in 1928.

Among Koopman's most ambitious projects was the recording of the complete cycle of all of Bach's cantatas, a project completed in 2005. Soloists for the project were among others Lisa Larsson, Sandrine Piau, Sibylla Rubens, Barbara Schlick, Caroline Stam, Deborah York and Johannette Zomer (soprano), Bogna Bartosz, Michael Chance, Franziska Gottwald, Bernhard Landauer, Elisabeth von Magnus, Annette Markert and Kai Wessel (alto), Paul Agnew, Jörg Dürmüller, James Gilchrist, Christoph Prégardien and Gerd Türk (tenor) and Klaus Mertens (bass). Koopman has received many prizes for his recordings. In 2005 he has commenced Dieterich Buxtehude – Opera Omnia, a project to record the complete works of Dieterich Buxtehude. As of March 2010, eleven volumes have been released. He was elected president of the "International Dieterich Buxtehude Society" in 2004.
