We're looking for a decent duet piece for our two euphonium players. It shouldn't be a cheesy piece and no pop-, film- or swing-arrangements or other easy-listening pieces are allowed. It should be a work that fits into the first part of a concert and should be written in a more classical / original way (it can, however, be an arrangement as well as an original work). It may also well be a slightly higher-graded piece. We went through most of the "Childs-Brothers"-CDs but couldn't find a piece that suits the purpose. Any hints out there?
