Born in Muret (Haute-Garonne), Ibos continued his musical studies at the Conservatoire de Paris, where he won first prize.
He was toured extensively to sing his repertoire, notably in Madrid, Brussels, Geneva, Vienna, and St. Petersburg.
[note 1] Since Ibos was a friend of Jules Massenet, the latter modified the score of the character of Werther, previously planned for a baritone, and remade it to suit the tenor role.
[1] The premiere was held at the Vienna State Opera[note 2] (in a German translation) on 16 February 1892 and the première in French at the Théâtre de Genève on 27 December 1892.
The Clément-Ader museum of Muret keeps the written archives (correspondence, photographs, sheet music, various documents), certain stage costumes, recordings, posters and props of this great tenor of the Belle Époque.
