ausArt is a Basque Classical label, specializing in 24-bit audio recordings.  What does that mean?  A CD — compact disc — is a 16-bit audio format.  That means there is some loss in fidelity of the recording.  If you use a DVD instead, you can get 24-bit audio and a higher fidelity of sound.  That is what ausArt does.  Their website goes into more detail and links to their online shop as well.  They also have a site dedicated to Basque composers with biographical information and includes free mp3 downloads of tracks.  They currently have a post about composer Juan Padrosa, who recently passed away.
