The musicologist Spilios Kounas, in the musicological analysis-documentation (prepared in the framework of the scholarship program of the Kounadis Archive) regarding the recordings of the song "Rast manes", which is part of the Kounadis Archive Virtual Museum, states the following:

"'San paradoso tin psychi ston charo ego gia sena, tote kai an me lypitheis ti ofelos gia mena?' ('If I surrender my soul to the Grim Reaper for you, then, even if you feel sorry for me, what’s in it for me?')

 It is a recording that follows the stylistic and aesthetic standards of the improvisational (a)manes. The melodic development takes place interactively between the singer and the violin, and the alternations in different interval structures are characteristic. It is worth noting that the rich management of the musical intervals of the melodic material, in addition to being a sign of high virtuosity, also suggests the complex way in which the musicians interpret the mode of the rast scale. In the recording, there is a motif that appears occasionally and functions as a rhythmic ison (drone note), which maintains the tonal center (tonic) that of the base. The performance is completed with a short improvisation played by the instruments, without turning the song into a musical theme-composition."
