Asturias by Isaac Albéniz
Asturias is a musical work by the Spanish composer and pianist Isaac Albéniz (1860-1909) The piece was originally written for the piano and set in the key of G minor but was subsequently transcribed for the guitar into E minor. ( https://youtu.be/oEfFbuT3I6A )
Asturias was first published in Barcelona in 1892 as the prelude of a three-movement set entitled Chants d’Espagne
The piece has become an important work of the classical guitar repertoire and has also been incorporated into all sorts of other music
e.g. Robbie Krieger, guitarist of The Doors, uses a reworking of the melody from this classical piece in The Doors song "Spanish Caravan" from their 1968 album Waiting for the Sun. (https://www.youtube.com/watch?v=6zrwCjjUqs0)
Also Children of Bodom attributed their Angels don’t Kill song to Asturias !(https://www.youtube.com/watch?v=cghYnVgx7KA)
It is amazing how one piece can be interpreted so differently!
