A deep-voiced Orthodox priest reads the Holy Gospel in Old Church Slavonic with a clear diction and reverent intonation. The delivery is not singing, but a traditional church recitative — measured, calm, without theatricality or emotional overacting. In the background, a small group of basses from a male monastery choir sustains a very quiet, low humming note (isocratic drone). No drums, no percussion, no lead instruments, no harmonies or backing vocals. Only the natural room reverb of an empty stone cathedral.
