Perhaps one of the few surviving operas by Biber? Perhaps others have been discovered since this one came to light? I am not sure.
However, lovers of the music of Heinrich Ignaz Franz von Biber may find this opera rather interesting. It features quite a colourful score and some fine orchestral writing. Of course, Biber always seems to love his strings and brass, and this score features a trumpet choir, a sackbut and strings. A recorder consort is also featured.
The soloists are good, many will be familiar with the Early Music stalwarts, Gerd Türk, Bernhard Landauer and Barbara Schlick, but most of the singers were new to me. The two countertenors are good.
The opera isn't a "great opera" as such, however, it does contain some great music. Some of the arias are worthy of Alessandro Scarlatti or Alessandro Stradella.
This recording was made in 1994 and it is a very high quality recording. CPO is to be congratulated for making this recording available to us.
However, I wonder if Arminio would benefit from the advent of DVD? Would this opera be better seen, as well as heard?
I hope another ensemble (perhaps Les Arts Florissants?) eventually records this opera for CD and, hopefully, DVD.
In the meantime, this recording is a fine account of this unique opera.
