Asturias, composed by Isaac Manuel Francisco Albéniz y Pascual (1860-1909):
The above piece was originally written for piano, but the transcription for guitar is particularly beautiful and captures the spirit of Asturias, Spain, and has become one of the most important works of the classical guitar repertoire.
For whatever reason, I find this piece particularly-evocative listening on a summer's evening.
