UAK was founded in 1944 by Svend G. Asmussen, who was its conductor the first 20 years. After him followed some of the best conductors of the country such as Niels Moller, Kare Hansen and Soren K. Hansen. Since 1988 Flemming Windekilde has been in charge and today the choir counts 30 members.
UAK first launched itself as an interpreter of Danish choir music but has since extended its repertoire to include European (mostly English, German, Italian and French) and American music - not to forget the inspiration from East-Europe and South-America. The music is classically orientated ranging from the Middle Ages to contemporary compositions, however, the music of the last and the present centuries being most represented.
The choir gives approximately 10 a cappella concerts a year and, in addition, arranges or participates in bigger perfomances with instrumental accompaniment such as Anton Bruckner's Mass in E minor, Bach's Christmas Oratorio, Arvo Pärts' St. John's Passion (1994 and 2000), Totentanz by Hugo Distler (1995), and a first performance of Scandinavian compositions as a part of the Copenhagen Cultural Capital Festival in 1996.
UAK travels often and has so visited Germany, Sweden and the Baltic countries where UAK had an exchange-project with the Latvian choir Ave Sol. UAK has also participated twice in the international Bela Bartok choir-competition in Debrecen in Hungary ( in 1992 and 1998) both times winning the third prize.
Austria (1994), The Czech Republic (1995) and Belgium (1996) are also countries in which UAK has participated in choir competitions. At the tum of the year 1992/1993 in connection with the celebration of the 75 anniversary of Demnark's cession of the Virgin Islands, UAK tributed with several concerts and in 1999 UAK visited Argentine.
