Chorus sine nomine, founded in 1991 by Johannes Hiemetsberger, is one of the most distinguished and innovative concert choirs in Austria. On this album, the choir presents motets by Anton Bruckner. Bruckner simply called them sacred choruses, as the reason for their composition can usually be traced back to a liturgical occasion. The six works on the album correspond to such liturgical interlu-des: Graduale (Christus factus est, Locus iste, Os justi, Virga Jesse), Offertorium (Ave Maria) and a hymn for the Good Friday liturgy (Vexilla regis). As an organist, Bruckner was admired above all for his improvisations. He was particularly admired for his high contrapuntal skills, in which he demonstrated his craftsmanship in fugue and imitation. The style of the fugal parts of his improvisations was based on Baroque patterns (such as Handel), while in other, more imaginative parts the tonal language of his organ playing became increa-singly typical of Bruckner. Martin Haselböck establishes this connection to Bruckner with his organ improvisations.
