July 1850 performances at Her Majesty's Theatre, London

In July 1850 Martínez appeared in a divertissement at Her Majesty's Theatre in London called Les Delices du Serail, set in a seraglio. After the curtain came up, a Sultan was shown amused by the dances of odalisques. Martínez then appeared "attired in a suit of rich amber-coloured satin" and performed.^[5] Her debut appearance at the theatre had been twice delayed by the closure of the theatre as a result of the death of Prince Adolphus, Duke of Cambridge, and her vocal hoarseness.^[4] The Times wrote that "the expectations of the public...were not a little wound up".^[5]

In London Martínez was marketed as the 'Black Malibran', in reference to the Spanish singer Maria Malibran. Edward Walford, writing in Old and New London (1878) wrote Martínez "sang quaint Spanish melodies". The opera manager Benjamin Lumley wrote in his History of the Opera, that Martinez's songs were "full of original charm, her execution excellent, her voice sweet, pure, and true; but the whole performance was small almost to meagreness, and, although it might well be regarded as a piquant musical curiosity, it failed in any real power of attraction".^[6] The Illustrated London News described her voice as "wild, quaint and graceful" with its "dominant qualities" of "picturesqueness and its strong and unanticipated contrasts" and described her vocal quality as "sweet and luscious".^[4] The Times wrote that her singing was "quaint and pointed, especially when she seems to give vent to a flow of spirits".The Times wrote that "much applause" followed each song, but concluded that "enough disapprobation was mingled with approval to render it pretty certain the Cuban style of vocalisation will not get a permanent foothold in this country".^[5]

Martínez's race was frequently commented on in contemporary accounts.The Illustrated London News wrote that "the fame of this lady had reached us and as a mark of social progress in the 'black race' was to us fraught with peculiar interest".^[4] The Times wrote that the appearance in one of the boxes of Her Majesty's Theatre of "a lady of colour has caused much conversation in the lobbies".^[5] Later 19th century accounts of her used racist language. In a chapter entitled "The Desecration of the Stage" in the periodical Time, an anonymous writer wrote that "the idea of nigger minstrelsy had not yet suggested itself" before Martinez was introduced to the "English opera goer" after a "great flourish of trumpets" and lamented the contemporaneous appearance of the Mastodon Minstrels.^[7]

Paris, France

Martínez resided in France around 1858–1863. The French writer Théophile Gautier corresponded with Martínez while she was in Paris earlier in 1850, marveling at "La Malibran" and recommending her to various theaters and operas.^[8] Between 1856 and 1859 Félix Nadar took a series of studio photographs of "Maria l'Antillaise", thought to be of Maria Martínez.^[1] She continued to struggle financially while performing, and transitioned from performing in operas and theaters to cafes, such as the Alcazar at 10 rue Faubourg Poissonnière. Charles Baudelaire wrote of her in a letter to Apollonie Sabatier, "Did you know that the unfortunate [l'infortunée] Mrs. Martínez was hanging out in the lyrical cafes and that she was singing a few days ago at the Alcazar?"^[9] She did not find the success of her earlier performances, and returned to Spain in 1863.
