Sabicas (Agustín Castellón Campos, 16 March, 1912, Pamplona, Spain - 14 April 1990, New York, USA) was a Flamenco guitarist of Romani origin.
Sabicas began playing guitar at the age of 4 and made his performing debut 2 years later. His early style was influenced by Ramón Montoya. Extensive collaboration with important cantaores (male Flamenco singers) of the period helped him develop his unique personal style.
Leaving Spain in 1936 during the Spanish Civil War, he went into exile in South America with bailaora (dancer) Carmen Amaya.
