I have listened to numerous recordings of these great Beethoven works, and Harnoncourt's is by far the best. The quality of recording, on top of the superior interpretation, makes it a must for any collection. I can say that the Coriolan Overture (track 1) is by far the most frightening example of this work I've ever heard (and this is a good thing!). Listen in particular to the horns in the recapitulation--it'll make the hair stand up on the back of your head. As for the Leonore III, the tempo WORKS! (as opposed to many others I've heard), and the big chord in the coda is positively orgasmic. Perhaps the greatest compilation of wonderful overtures of LVB ever created.
