Ruders writes: 'gl0rIA' is subtitled: 'a relique for large chorus and 12 brass-instruments. At the same time it is an exercise for chorus because only vowels do occur or virtually no consonants are heard. The second part of the Missa Ordinarium the Gloria in Exelcis Deo makes the literary basis of 'g10rIA' but I employ only the vowels which in their full context form a 'non-language' - fragments of a tradition. A less dim vision of the 'severed body' appears in the center of the piece where the Domini Fili-section surfaces in its original shape. 'gl0rIA' is a 20th century composer’s hommage to the innocent faith of bygone days and a fanfare in honour of ClaudioMonteverdi; thus the ever present elaborations of the introduction to the Vespro Della Beate Vergine. Superimposed on the 'torso' of Latin I wedge in a quotation from the Spanish renaissance poet Gonzalo de Berceo’s 'Duelo de la Virgen' a surrealistic Lamento in which the Jews sent by Pilate to stand guard at the tomb of Christ mock and ridicule Maria Jesu mother. Thus a shadow has been cast over the jubilant religious appraisal of the past which today’s knowledge of atrocities and enormities engineered by Mankind has - alas - made so hard to repeat.

The composition Kefas was written for the brass band 'Apollo' from Grou (The Netherlands) by order of the Unisono Foundation the organisation for wind music in The Netherlands.The assignment was given on account of earning the Champions Title during the Dutch Brass Band Championships in the year 2001 (4th division). The theme of the composition links the tradition of the village Grou not to celebrate Sint Nicolaas but Sint Pieter.By this typical Dutch festivity (in December) the holy Nicolaas gives presents to the children. It is a popular custom where young and old participate. Grou is the only place where this is not done by Sint Nicolaas but by Sint Pieter.Apart from that on the 22th of Februari a lot of festivities that take place resemble those of the Sinterklaas celebration. In the composition two Sint Pieter songs are processed set through bible scenes wherein in among others the visit of Christ to the house of Peter's Mother-in-law and the calling of Peter are depicted. The title refers to the pronouncement of Christ where he named Peter the rock on which he shall build his church. The Hebrew word for rock is Kephas. Kefas was premiered in 2003.
