The setting was originally written in Church Slavonic (the language used in the video below), but it has been translated into Latin as well. For all I know, there could be English versions out there, too.
When people think of Stravinsky they probably think of the Rite of Spring or something like that. In his orchestral pieces rhythm reigns supreme; there is a drive to it that is decidedly instrumental and even mechanical at times. This is not the case in the Pater noster: the text determines the rhythm. In a certain sense it almost seems like the measures could have been laid out by Dom Mocquereau.
