Spanish classical music often means guitar, and this piece is one of the most famous of the guitar works. Albéniz was a child prodigy who applied to the Paris Conservatoire at the age of seven, and who toured internationally by 12. Sadly, he died at 48, but left us this work.
This music would have come to us via the Musopen project, a 501(c)(3) organization that hires musicians and orchestras to record great music that is released into the public domain. They have a growing library of MP3s from Beethoven to Bartok, all free to download and share. Free as in released under the Creative Commons Public Domain License. If you love classical music, you should stop by and browse.
Sadly, Blogger doesn't seem to let you upload MP3s to your blog posts anymore.
As with the spirit of Creative Commons, if you like the downloads, you might want to consider donating to Musopen. As they get more money, they hire musicians to record more music. They also have sheet music in PDF format, again released to the Public Domain.
