Music is for enjoyment, and one of the greatest pieces of advice my former-pro guitarist mentor said was &quot;Audiences don&#x27;t like it when you play over their head.&quot;<p>I&#x27;m all for expanding the universe of good tunes that orchestras can play, especially if that keeps orchestra members able to make money and continue their art. There&#x27;s a small part of me that can see the perspective of the purist, but it reminds me too much of &quot;formal musical study&quot; of the guitar, which is, essentially, playing a lot of classical stuff that most people aren&#x27;t interested in hearing! The jazz guys and gals maybe have a bit more approachability, but again, the peak of the genre is very complex and out of the usual scope of &quot;listening for pleasure.&quot;<p>I haven&#x27;t been to one of these (yet) but I&#x27;d surely like the chance to experience it. Also, somewhat relevant, the last time I checked, the &quot;Trans Siberian Orchestra&quot; holiday performances were hanging in and probably making some good money! I know they got my cash one year.<p>Times change, tastes change.
