Isaac Manuel Francisco Albéniz y Pascual was a Spanish virtuoso pianist, composer, and conductor. He is one of the foremost composers of the Post-romantic era who also had a significant influence on his contemporaries and younger composers. He is best known for his piano works based on Spanish folk music idioms. Isaac Albéniz was close to the Generation of '98.
Transcriptions of many of his pieces, such as Asturias, Granada, Sevilla, Cadiz, Córdoba, Cataluña, Mallorca, and Tango in D, are important pieces for classical guitar, though he never composed for the guitar. Some of Albéniz's personal papers are held in the Library of Catalonia.
