John Piper sermons

I love John Piper's books and most of his sermons. The trouble with listening to him sometimes is that you really have to pay attention to every single word or you may miss the weight of what he's really saying.

I love his biographical sermons and found great encouragement in his sermon on Adonorhim Judson.

Does anyone recommend some other sermons by Piper that would be great to listen to (and take notes)?
