Paul Irish‘s brilliant MP3 blog more often than not proves the truth in its tag line: “your favorite music you’ve never heard.” Here you will find a collection of music from genres multifarious, and more than likely scarcely known in this country. The wide range of international artists probably contributes to their lack of eminence on these shores, but most are worth a listen. Even better than the listening itself, of course, is the download-ability of the featured tracks. And best of all, in my opinion, is that Aurgasm fetches permission from the musicians it features.
You would do well to check it out and spend some time digging through the archives.
