For me, actually deciding to go to a concert (of any type of music), my first consideration is if l respect the artist, or artists that are performing. Sometimes it can be the conductor of the orchestra that over rides even the music performed.
There is nothing quite as thrilling as hearing a 100 piece orchestra conducted by the actual composer, who best knows how the music should be performed.
The same applies to a pop or rock group if the original members are still present to reproduce the songs as intended, or add embellishments and refinements they have adapted to over the years. Often the degree of professionalism and musicianship has matured over the years too, and the performance now is far more refined.
Those are the two main reasons why l will still selectively attend live concerts. Of course the original records or CDs remain the original focus point as to why l liked the music, and those first impressions. I like the best of both worlds.
