Purchasing DVD or blue ray recordings of live orchestral performances


I am very excited to hear some suggestions on where to purchase DVD or blue ray recordings of live orchestral performances. Can you guys suggest me some?

There is a whole new world out there for you.I like elusivedisc.com,musicdirect.com & Amazon.com..There are also a ton of concerts posted on uTube.com,try searching specific performers or Composers..Another avenue is many city symphonies have performances available on media for sale..Good luck & enjoy!
