A few channels on YouTube have posted songs from Smoke + Mirrors Live. I found a video where Dan talks to Toronto for a bit, and then the band plays It's Time. This is where he reveals to them that the concert is being filmed.
I live an hour outside of Toronto! I was disappointed to find out that in July 2015, there was an amazing concert going on in Toronto and I wasn't able to go! Oh well, I probably wouldn't have been able to be there anyways...
Here is the video: https://www.youtube.com/watch?v=vYgzKX8ogCo
There is also a great video where the band performs an acoustic version of Thief - this is the first time that Imagine Dragons have ever performed that song live! Dan looks so happy to be there, in front of all those people.

I am definitely hoping to get Smoke + Mirrors Live at some point!
