The male choir "Optina Pustyn" was founded in 1996 in the Cathedral of metochion of Optina Pustyn in St.Petersburg. From the first days of establishment, the choir continues to add to its liturgical repertoire of ancient and modern ecclesiastical chants. The result of the activities of the choir was a performance of many singers' manuscripts from the collections of academic libraries that have found their new sound in the worship compound. In addition to ancient Russian styles of singing such as: znamenny, putevoy & demestvenny chant’s, znamenny polyphony and partes, the choir sings chants of the Orthodox singing traditions in Greek, Serbian, Bulgarian and Georgian, as well as modern arrangements of ancient chants and religious hymns by Russian composers.

The founder of the choir, artistic director and choir director, Alexander Semyonov, graduated from the conducting and choral faculty of the St. Petersburg Conservatory under V. Borisov, the elective of symphony-conducting in the class E. Serov, and furthermore, studied ancient Russian notation. The ensemble is composed of professional soloists - graduates of the St. Petersburg Conservatory. It consists of an honor artist of Russia, soloist of the State Choir Chapel & the Mariinsky Theatre Vladimir Miller (bass profundo), and laureates of international competitions: Alexander Gorbatenko (counter-tenor), Dmitry Shishkin (bass), Boris Petrov (baritone), Andrey Ivanushkin (regent and tenor), Victor Khaprov (bass), Nikita Tchernikov (tenor), Ivan Egorov (tenor), Sergey Grigoriev (regent and bass).
