One could easily imagine that a programme such as this, of 29 thirteenth-century motets, all composed around the same theme of fin amours and all sung unaccompanied by an all-female vocal ensemble, might end by becoming wearisome on the ear. Anonymous 4 have proved conclusively in this recording that this need not be so, that, in any case, there is already an infinite variety of mood and style among the songs-compare, for example, No. 14 (Joliement/Quant voi la florete/Je sui joliete) with No. 18 (Ne m'oubliez mie)-and that it is possible further to vary them in performance, using no other means than the voices themselves.The directness of the group's approach is always refreshing: their tone is unaffected, their pitch secure. The songs are presented with simplicity in a clear acoustic. There is a total absence of any improvised doodling on reconstructed medieval instruments, which is rather a relief. One gets a sense of quiet satisfaction and enjoyment from the singers themselves. I also get the feeling that the singers are trying to teach us something about the music, the mechanics of the motet and how it works, almost as if they were demonstrating to a class of music students. They sometimes go out of their way to sing a single part and then to repeat it with another part added, and then finally to give us a polished rendering of the whole motet, complete with all its parts. Occasionally they add a drone-once with a doubling at the fifth above.
