Britten's Missa Brevis and Pergolesi's Stabat Mater have long become label performances of the Sofia Boys' Choir. Established in 1968, since 1989 onwards this formation has been under the leadership of Adriana Blagoeva, who expanded to a great extent the choir's repertory, including in it large-scope cyclic musical works from the past and the modern times.
Among the numerous works of the great English composer Benjamin Britten the opuses associated with the English religious musical traditions from the Renaissance epoch deserve a special mention. Among them stands out Missa Brevis, performed by the Sofia Boys' Choir and the organist Atanas Atanassov with remarkable musicality and vivid portraying of each of the five movements of the Missa. To combine Britten with the Italian composer Pergolesi is an excellent idea of Adriana Blagoeva, the conductor, who has worked out in details and in a very good style the poly-movement composition Stabat Mater - a classical example in the genre. The solo parts performed by the famous opera singer Hristina Angelakova, mezzo-soprano, and the soprano Theodora Gabrovska are incorporated in the magnificent sounding of the children's choir. Pergolesi's music captivates with its melody, harmonic symmetry, contrasting character and mastership in interlacing the motifs in a polyphonic construction, all that sung in excellent sonority and with precision by the Sofia Boys' Choir.
