A very gifted person, he perfected his talents in singing, bandura playing, ethnography, journalism, education, design, and architecture.

Kobzar Ivan Kuchuhura-Kucherenko stayed with him in Myrhorod in order to refine his performance of dumy (sung epic poems) under the guidance of Slastion.

Danylo Pika, one of the founders of the Poltava Bandurist Capella (who became its conductor), initially learned to play the bandura from Slastion in Myrhorod.

In 1875, then a student at the Petersburg Academy of Arts and a budding folklorist, he spent his holidays in Ukraine and got the chance to know the artistry of the kobzar Nekhovaizub.

These recordings were transcribed by Filaret Kolessa, who later published them in his collection Melodiyi ukrayins'kykh narodnykh dum (The Melodies of the Ukrainian Folk Dumas).
