At the end, there was a dead silence of 3 to 5 seconds before audience applause.
3-5 seconds?! You call that a "pause"?! Check out the seldom performed (especially on the radio) piece by John Cage titled 4:22. In it an entire orchestra takes the stage and for 4 minutes and 22 seconds does not make a sound, then they leave the stage. I'd bet the applause on that one can be delayed too. Never had the pleasure of attending a performance though.
Actually there are some modern composers I really do like. Arvo Part comes to mind. Some pieces by Phillip Glass are quite lovely. Gavin Bryars stuff is out there and yet somehow moves me. The Rachel's are another group who use their backgrounds in classical music to compose and perform music that defies conventional classification. I do like Motzart too! Beethoven, even!
Do you recall what it was you were listening to on the radio Eldartford?
