It is early May 2011, and twenty musicians find themselves together for the first time in a recording studio somewhere in Brussels. Producer, bass-player and musical ringleader Vincent Kenis is marshalling his troops: half of them represent ‘Congotronics’ – drawn from the ranks of Konono N°1 and Kasai Allstars – the other half are ‘Rockers’, flown in from the States, Sweden, Argentina and Japan. The atmosphere, according to Matt Mehlan of Skeletons, is “intense”.
