Personally I find Bach's 200+ cantatas a source of almost endless tedium, but occasionally a movement or aria turns up which is a real gem, and this is one, in my opinion. It's the opening aria from Cantata No 170, "Vergnügte Ruh, beliebte Seelenlust", sung by Polish countertenor Jakub Józef Orliński, who, until today, I confess I had never heard of (but he's very good).
Spare textures, beautiful oboe obbligato. Just don't fixate on the hyperactive violinists, especially the one next to the oboist, whose knees seem to have a mind of their own.
For me, Bach doesn't get much better than this (your mileage may vary, of course).
