I know there was this sort of sicilian scene with bands like Inchiuvatu, Lamentu, Ultima Missa, Inquietu, Astimi and others. I never checked them out, so... what are the good bands and albums?

I dont know about this bands, but Malfeitor and Noctifer are from that scene. Noctifer kind of bores me, not bad though. Malfeitor kicks ass though, and they only have one album, so listen to that

I already know Noctifer and Malfeitor, and they're not Sicilian, they're from Rome.
