Ich habe genug, BWV 82, is a church cantata completed in 1727 by German composer Johann Sebastian Bach (1865 - 1750). Of the 200+ Bach cantatas that are known, this one for bass without choir is my favourite. The aria "Schlummert ein, ihr matten Augen" reaches the same dazzling heights as the most beautiful parts of his passions. The cantata is in five movements (details in the WikiPedia entry), and the average playing time is 23 minutes (AllMusic). I have two versions, both great, but I have a clear preference for the one by Dietrich Fischer-Dieskau with the Munich Bach Orchestra under Karl Richter on a Deutsche Grammophon/Archive CD).
