Just watched a VLOG Jason Jani put up a year ago. Great Lighting set up. He has a crew like Taso does at the wedding with him.
I will say though, that he can improve his MC technique. I heard "Ladies and Gentlemen" ..."Ladies and Gentlemen" ..."Ladies and Gentlemen" a bunch of times in the video to the point to where it annoyed me a bit. Just a little pet peeve of mine. I try not to use the term more than once during the entire night at a gig. I hate being repetitive.
Having someone play the music while being out in the open is great to do though!
I have only done it once, and it was nice to talk to the crowd out in the open.
