"Joy in the Congo" on tour

The Kimbanguist Symphony Orchestra (OSK) is based in Kinshasa, the capital of the Democratic Republic of Congo (DRC). Having gone through decades of war, the DRC is a fragile country and among one of the poorest in the world. But those challenges have never deterred the 200-member orchestra and choir from playing and composing beautiful classical music. The OSK will be celebrating its 20th anniversary, and we thought it would be nice to see what they've been up to since they were first introduced on 60 Minutes two years ago.

The following is a script of the video produced for 60 Minutes Overtime by Magalie Laguerre-Wilkinson and Sarah Shafer.

60 Minutes first profiled Congo's Kimbanguist symphony orchestra in 2012.

[Bob Simon in 2012: You had no musicians, you had no teachers, you had no instruments.]

[Armand Diangienda: Yes.]

[Bob Simon: And you had no one who knew how to read music.]

[Armand Diangienda: No, nobody, nobody.]

Since then, the orchestra has gained some notoriety -- the string section and their conductor, Armand Diangienda traveled to Los Angeles last year.

Armand Diangienda: I was traveling with them; I couldn't believe I was there with them in the plane. I cried in the plane, I said, "Oh my God, things became true now." So I'm really happy to be here.

They played for the L.A. Philharmonic's conductor, Gustavo Dudamel.
