Neither Isaac Albéniz (1860-1909) nor Enrique Granados (1867-1916) wrote any guitar music. Their solo music was written for the piano, though several of each of their pieces are well-known from guitar transcriptions. The guitar acquired its prestige, and attracted serious composers, later.
Here are transcriptions for orchestra (I don’t know by whom) of Andaluza (which means woman of Andalucía; the piece is not really suited to orchestra, but it’s enjoyable anyway) by Granados, from his twelve Danzas españolas of 1890, and of Triana (which is a part of Seville) by Albéniz, one of the twelve, more substantial, pieces in his Iberia of 1908.
Enrique Jordá, Paris Conservatory Orchestra, recorded in 1950, from an early mono LP. The artwork gives 1888 as the date of Andaluza and 1905 as that of Triana, which may well be the dates of composition of those pieces.
Granados and his wife Amparo drowned on March 24 1916, when a German U-boat torpedoed the French passenger ferry Sussex while it was sailing between Folkestone and Dieppe. They were on their way back from New York and had missed the boat which would have taken them from there direct to Spain (A Coruña?). Granados had jumped out of his lifeboat to try to save his wife.
