I saw them five or six years ago with Massilia Sound System, a reggae/ragga group in which the singer and the guitar/banjo player are involved. Though I knew well Massilia Sound System, I hadn't heard anything about Moussu T e lei jovents. It was a great time and few days after this night, I listened to their first record.

Moussu sings both in french and in occitan, mostly about Marseille and La Ciotat and the everyday life of people. On the first record, there's a beautiful song called "Paul Emile et Henri" about the poor people who faught and died during the World War I : http://www.dailymotion.com/video/x47724_moussu-t-e-lei-jovents-paul-emile-e_music
