This is part of the Martin Scorsese's World Cinema Project DVD box set which included five other films: The Housemaid, Dry Summer, Redes, Touki Bouki and A River Called Titas. Bought the DVD box set as I saw the first two films online at mubi.com and was impressed by them!
The story is about a famous band in Morocco named Nass El Ghiwane.
Liked the nice songs and music in the film! The lyrics of the songs seemed quite meaningful too!
