Trente Oiseaux pour rien!
The fantastic and influential Trente Oiseaux label, run by the fantastic and influential quiet electronic composer Bernhard Günter, has begun offering free flac downloads of many of their releases. Feel free to sample about, but I HIGHLY recommend the classic Günter albums Univers Temporel Espoir and Un peu de niege salie. Note that, at least when I downloaded, Details Agrandis was inexplicably LOUD and was not at all pleasant.
