An email from ECM today indicates it's Dino Saluzzi's 85th birthday. Not familiar with him I find out he's an Argentinian bandoneon master. I've developed an interest in the bandoneon since starting to listen to Astor Piazzola's music, so I have to check this out.
Really like this pressing. Very clean with excellent dynamics. The Analogue Productions 45 rpm set may be bit quieter in the groove, but this issue is nearly as good and you don't have to change sides every 7-8 minutes.
