Juan Cristóbal Martín (born c1945, Málaga) is a Spanish flamenco guitarist and an author of flamenco guitar method books.
Martín started learning the guitar at the age of six. In his early twenties he moved to Madrid to study under Nino Ricardo and Paco de Lucía. He played in clubs in Málaga, Seville and Granada. He soon moved to London, where he has developed most of his career. One of his first recordings was Picasso Portraits (1981) based on the music he played at Picasso's 90th birthday celebrations. Each section is a depiction of a painting by Pablo Picasso. Although it was not released until the 1990s, he recorded a track with Rory Gallagher in 1984 (on the album, Wheels Within Wheels). Also in 1984 his track "Love Theme from The Thorn Birds" reached number 10 in the UK Singles Chart. He recorded with Herbie Hancock in 1987 and has played on stage with Miles Davis.
Juan Martín is the author of two flamenco guitar methods, 'El Arte Flamenco De La Guitarra' originally issued with cassette tapes and later with vinyl sound sheets, and 'Solos Flamencos' issued with CDs and DVDs. Both methods, printed in English and Spanish, are very successful in the English-speaking world.
