Free(ish) music and costly involvement
I particularly enjoyed the atmospherics of BANG! and Train in the distance, and the emotional impact of a visit to Africa is clearly evident.
Even if the music doesn't do it for you, take the opportunity to find out about GLO's incredible work in Burundi, and its founder Simon Guillbard, an incredible guy whose book, For what it's worth, asks some of the hardest questions in the Bible with genuine integrity.
