Deletion of Valerian shiukashvili

Comment: WP has scores, perhaps hundreds of piano competitions, so the bar doesn't seem that high, and yet none of the competitions listed in this pianist's resume are to be found here. The subject does not appear to have played with major ensembles or at major venues, does not appear to be represented by an artist management company, does not appear to be a faculty member of a major or indeed any conservatory, and I could find no evidence of recordings, other than the live recordings that can be played on the artist's website, plus a couple of youtube videos. Cited sources and web search results appear to be trivial and/or non-, primary, or social media. Fails . If better sourcing can be found, I will gladly reevaluate
