While quarter-tones can be somewhat problematic (choruses can have a relatively fuzzy pitch band for sub-semi-tone divisions), I have heard Chanticleer give a totally convincing performance of Scelsi’s “Tre canti sacri” (which has them), a chromatic pitch vocabulary is not inherently un-chorus, even if it’s a little less common. I would cite any number of pieces recorded by the Eric Ericsson Chamber choir, the Danish Radio Choir, the Finnish Tapiola choir (children!), and the excellent work of Donaly Nally with The Crossing (Philadelphia) and San Francisco’s Volti Chamber Choir [disclaimer: I'm Volti's resident composer].

Otherwise, great reivew.
