The opera singer voice was unique – of great volume, flexible, mellow, with soft timbre; it was voice of comprehensive vocal range - from great octave F (very low note) to A-flat of one line-octave. An outstanding master of phrasing with excellent enunciation and artistry.

It is noteworthy that in 1980, at the age of 85, Mark Reizen performed the part of Boris in the opera “Boris Godunov” by Modest Mussorgsky; and in 1985, at the age of 90, he sang the part of Prince Gremin in the opera by Tchaikovsky opera "Eugene Onegin" on the stage of the Bolshoi Theater - for which he was enlisted in the Guinness Book of Records as the oldest acting opera singer in the world!

For Mark Reizen birthday, we have prepared a musical selection made up of opera parts and romances performed by the prominent opera singer. The biography of Mark Osipovich Reizen is in the section "Authors/Producers".
