The interview
In an interview that was given to Mr G. Stathopoulos and broadcasted by L. Angelopoulos on radio we hear the following interesting things by the man that not only met Konstantinos Pringos in person but also wrote down many (if not all) of his compositions.

GS) How did Pringos chant?

AE) Although he wasn't highly educated, he would get transformed to something surrreal while chanting.

GS) Are you a Pringos' student?

AE) I am everybody's student

GS) Did Pringos have any real students?

AE) No he didn't. Those who claim they are his students and present diplomas are plain signed statements that they brought to him to sign. (Stanitsas would disagree, according to the book of X. Tsiounis)

GS) Are there any modern Pringos?

AE) No, only corrupted copies.

GS) What does it mean to be a psaltis?

AE) To understand what we are saying when chanting and to whom we are saying it to. We have learnt how to shout and make an impression with our voice, but that isn't the point.

The whole interview given to (now Fr.) Georgios Stathopoulos [mp3] including some chanting by Archon kyr-Avraam Efthemiadis at the age of 90!
Recordings
