Yo Yo Ma Concert at McCallum Theatre

So I've missed the presale/onsale for this show. Now the venue is sold out. The resellers want upwards of $2000 for balcony seats! This is outrageous!!! Is there any way to get a hold of some tickets for the show at a reasonable price? My wife and I have been dying to go but definitely don't have $4000.

If anyone can help me out here, let me know. Thank you
