Each Wednesday evening  I come home. @the centre of Brussels, @DeMarkten. @(info) STEMMER. Up to 50 people, full concentration, but equally so drinking and chatting. All fully engaged to study, to perform, to show themselves as a « secret city choir ». They performed in several adventures, and now, again, they help me to be the backbone of this large MixitySings project. Hence : Best Friends Forever. BFF.
