Duo Constructor was founded as a pure Acoustic-Guitar-Duo in November 2002.
The basic idea behind it, is to play a good mixture of different styles like Irish-Folk, Rock, Pop, Blues and Ballads - without too much technical expenditure.
The whole setup is made of their own songs, written and composed by both Udo and Joe.
October, 16th 2004 saw the release of the first album "On The Run", introduced with a live concert in Joe's hometown.
On stage, the additional instruments are often played by varying guest musicians.
