By any measure Rafał Augustyn's Symphony of Hymns is a big piece. It clocks in at 100 minutes; requires forces of more than 170 performers, including two solo singers, electronics and solo flugelhorn; sets texts from 20 sources by 17 authors in five languages; and took its composer 20 years to write. But for all its scale, what is perhaps most impressive about the work is that across these dimensions Augustyn has written a score that is always inventive and enjoyable.
