Eloy is a German progressive rock band, whose musical style includes symphonic and space rock, the latter theme being more prevalent on earlier albums. Despite their nationality and time period, the band is not generally considered krautrock because of their sound, which has much more in common with English symphonic rock groups such as Pink Floyd, King Crimson, Yes and Camel. Founded in 1969 by guitarist Frank Bornemann, the band has endured several line-up changes, with Bornemann being the only consistent member of the group. In the 1980s, after a series of major splits in the group, Bornemann pursued a more commercial direction. Despite attracting a large following in Germany, the band never gained popularity in the United States.

However, in later years, former members of the band re-joined, and in 1998 released the album Ocean 2, a return to the classic symphonic progressive rock genre for which the band was well known.
