The performance of Fratres, for violin & piano with Gidon Kremer and Keith Jarret from the 80's is one of the best classical performances in my collection. It's so amazing, and with good headphones, the timbre of the violin and Kremer's high notes are absolutely gorgeous.

I was lucky enough to see a performance by the Estonian Festival Orchestra in the Berlin Philharmonics a few years back. The whole full big room was dead quiet and listening, it was so good.
