HAZ (30.06.2006) On "The clazz Files"	A November feeling "Outside the June sun is blazing, however inside it is dark and sombre, and Sting's sorrowful "Fragile" resounds. Around 40 young men and women are singing. And yet the refrain sounds like just a quiet breath. It is melancholy and Novemberish in the Eisfabrik in Hanover's Südstadt. But it all started so summery: The young Hanoverian Concert Choir clazz opened the program […] with such upbeat songs as "Blame it on the Boogie" and "Good Vibrations". Then the high point: "Ride like the Wind" by Christopher Cross as a fast tempo a cappella version. It is a small vocal firework display: imaginative and multifaceted. […] the performance of the choir, which is well-known beyond Hanover for its versatility, has charm and supplies a few original surprises [..]"

Südwest Presse 11. Juni 2003	„The choir with 15 female and 13 male singers scintillated with a cheerful atmosphere...“ „...the singers again and again succeeded in fascinating the audience.“ „The well-known song "Let the Sunshine in" from the musical "Hair", or other popular oldies like "On the sunny side of the street", "Good vibrations", "Walking on sunshine" and "Follow the sun" to name just a few, increased the audience's good mood. This resulted in the enthusiastic audience's demanding two encores after the finely-sung evening song "Der Mond ist aufgegangen".“
