2 in E minor, WAB 27 is a setting of the mass ordinary for eight-part mixed choir and fifteen wind instruments, that Anton Bruckner composed in 1866.

The bishop of Linz, Franz-Josef Rudigier, had already commissioned a Festive cantata from Bruckner in 1862 to celebrate the laying of the foundation stone of the new cathedral, the Maria-Empfängnis-Dom.

those by Roger Norrington, Hellmut Wormsbächer, Philippe Herreweghe, Simon Halsey, Frieder Bernius, Ingemar Månsson, Helmuth Rilling, Marcus Creed, Winfried Toll and Otto Kargl.Bernius particularly insists on the modernity of the score: the Mass is heard here in all its audacity.

The highlight of the Mass is the poignant "Dona nobis pacem" in the Agnus Dei.The music lover, who wants to experience the "environment" of a church interior, experiences with Kargl an atmospherically dense, dark, murmuring, sonorous recording with convincingly captured church acoustics – a recording that is able to captivate the listener.
