Repointing to opera 2595 Alessandro Severo. This recording was filed under opera 1267 Alessandro HWV 21, but its cast - Salustia, Giulia, Albina, Claudio, Marziano - is the Alessandro Severo HWV A13 cast; HWV 21 has Lisaura, Rossane, Tassile and Leonato. The error made 7990 and 9612 look like rival recordings of one opera when they are recordings of two different works, both under Petrou.
