[78-L] Date on Juan Valls Columbia Record

[bruce78rpm at comcast.net]

I found a Cort Label (Columbia Client Record) with a Columbia Matrix of 10611, The artist is Juan Valls Tenor, title is "Esulate e ora per Sempre Addio from Otello. He is accompanied by a Pianist who sounds like he is pounding the keys with his fist !! Maybe the recording engineer, told him to play really loud, because the piano does not record very well. Can anyone give me a recording date for this one ? 

Thanks, 

Bruce
