There have been great concert halls for hundreds of years. Many great ones available to us were built in the 1920’s. They are great acoustically and aesthetically.
I am not sure when I attended my first… probably Chicago in the 1960’s but I highly recommend it. Do not put it off. Do it soon. Find a great hall near you.
I have had the privilege of listening to live orchestra’s in great halls hundreds of times… it has been such a great experience and helped me so much in targeting what I wanted from my audio system.
