Wikipedia:Articles for deletion/Johannes Kretz
My searching did find an http://derstandard.at/1343743874150/Johannes-Kretz-Aufnahmepruefungen-sind-ein-heisses-Eisen interview but that doesn't help notability. The article sources provide some depth but that all seems to be self sourced like http://db.musicaustria.at/node/58224 this. Fails . The awards are notable and perhaps well known.  Which may be enough to satisfy
