...And Oceans, at one time known as Havoc Unit, is a metal band from Finland. It was formed in 1989 as a death metal outfit called Festerday, but soon changed its style to symphonic black metal. It released its first album as ...and Oceans in 1998, and in the following years it pursued a less traditional, more industrial-oriented direction.
