One artist I enjoy from Jamendo is Antony Raijekov, who has two (one and a half, really) albums there … Jazz U and See U. Both are collections of sorts, and I discovered via his Web site that most of his stuff is available as open source audio on archive.org.
Which leads me to my last music tip for a little while: When you get the chance, check out the 78rpms collection, which includes some fantastic, ancient recordings made from records from the early decades of the 20th century. Duke Ellington, Louis Armstrong, Jelly Roll Morton, Cab Calloway, Tommy Johnson, Charlie Patton and some others are there, as best recorded given the age of the medium and the limits of technology.
Most are encoded as mp3s, but some are available as ogg files and you can convert without fear of losing sound quality — because of the age of the recording. If you enjoy jazz or blues or even some early folk tunes, some of those recordings are the cornerstones of the genres. Enjoy!
