Best Orchestra Concert that You’ve Ever Attended

Please include the performer(s)/group(s) names, the pieces on the program, and why you picked this particular concert. For me it is the Detroit Symphony Orchestra's performance of Carmina Burana, absolutely marvelous. I am hoping and praying to God that I can attend the Berliner Philharmoniker's possible tour this November, where they are performing Charles Ives' Central Park in the Dark, Andrew Norman's Unstuck, and Strauss's Till Eulenspiegel and Ein Heldenleben. I chose the DSO concert because I remember being blown away by the size and power of the orchestra and choir performing, such a magical experience.
