"Just what was Berio trying to achieve in the meticulous, variegated, sensitive, textuer-obsessed, micro/macro-experimental masterpiece for 40 voices and 40 instruments that is Coro? ... Two features stand out: first, its tendency to put a revealing slant on Berio's particular form of expressionism by keeping it allof-a-piece - a single canvas; second, its prioritising of the composer's interest in merging instruments and voices to the point where on occasion neither is identifiable as one or the other ... Pedersen achieves both through judicious matching of individual voices to each other and to instruments ... Everytime this excellent choir issues a new recording you wonder what will come next, but there hardly seems anywhere left after this".
