Blast from the past - here's a nice instrumental song from the 1920s. Enjoy!
Song: William H. Reitz - Dill Pickles Rag (Xylophone Solo) (2:30 min, 2.3 MB)
License: Most probably Public Domain, as the song is from 1922. Please correct me if I'm wrong.
Purchase from: ?
One for the night: a nice, mellow, orchestral piece called "Sindomine", performed by Galdson.
Andrew K. Stone is the author of two books, but has also created this nice pop/rock song you're probably listening to right now... After an email conversation he kindly agreed to license his songs under a Creative Commons license and uploaded them to archive.org. Thanks Andrew!
And now: fine instrumental music with a good portion of percussion and violins, performed by Hans Christian.
