...Perhaps the most astonishing piece on the program was the wordless work that opened the second half, “Mouyayoum,” by Anders Hillborg, in which the singers, intoning sliding vowels, sound like instruments in some eerie celestial ochestra, sliding in on a whoosh of air from the void, occupying earth with their captivating babel, and exiting on another rush of air back to the void whence they came. It was mesmerizing — stunningly difficult, stunningly simple.

... The program here, though bolstered with the venerable sounds of Bach and romantic, pre-12-tone Schoenberg, was no conservative sampling, as indicated by the dynamic opening piece, by the young Swede Anders Hillborg. His unpronounceable piece "muocaaeyiywcoum" is a powerfully evocative, text-less celebration of vocal texture, coming across like a softly shimmering and slowly changing sonic mist.

...Anders Hillborgs Mouyayoum, som med körledarens ord är kanske det hittills mest imponerande bygget i den nordiska vokala minimalismen, 32 stämmor i vila och rörelse. Lyssna!

...en skimrande saga. En berättelse vars innehåll vi förstod före utvecklandet av det talade språket...
