Found several videos online and thought I'd just post them all here in one, with some comments.
The above video is from the Christ-centered worship portion of the program. These are some of the young adults and youth from TriEak Parmeshwar Mandali singing a worship song. The audio isn't very clear, but they did a great job.
This was one of the best performances of the night. These three ladies are (I think) from the Bhutanese community in Aurora. They perform here a traditional folk-style dance. So nice!
Finally, this is Narayan Gajmer from Chicago performing a song with the aspiring young Nepali rock band. Yes, that's a harmonica!
