There are two artists/groups known by this name:
1) Aurora Borealis is one of those death/black metal hybrids, with Vento's vocals slanting toward black and the riffing and drumming siding a bit toward death metal. There's an above-average degree of technicality here, as Vento is a solid guitarist and an adventuresome songwriter. The songs mix both technicality and brutality quite well -- this is a fine band well worth investigation.

2) Aurora Borealis is one of the aliases of Shazz (Didier Delesalle), under which he has published mostly trance techno on French label F-Communications.
