There is a good chance that Verna and I will be attending one of the weekly shows that Santana puts on at his club in the Hard Rock, Las Vegas. I have no idea how long these shows are but the tickets for the two of us would be in the balcony. For the two of us, they would cost a total of $130. The primo seating is much higher.
I've only seen Carlos one time live and that was at the Crossroads Guitar Festival in Dallas back in 2004 or 2005....somewhere along in there. He's amazing to watch (and of course listen to!)
