Still in a mood of unbelieving amazement about these incredible twelve guys I heard tonight at Gütersloh Stadthalle. Chanticleer is an a capella group from San Francisco, including two basses, one baritone, three tenors, and six countertenors (three altos and three sopranos). Everyone of them has an impressive voice in range and timbre, but together they really form an remarkable orchestral sound. Unbelievably good. They sung this little piece as an encore. Pardon my enthusiastic adjectives here, but they are well earned.
