Mekong Delta is a German thrash metal band formed in 1985 by Ralf Hubert with the goal to "musically outshine" all other independent releases at the time.

The band was founded by a group of German metal musicians with the goal to 'musically outshine' all then-current, independent releases.

The entire project was started by Ralf Hubert, sound-engineer for Warlock, Steeler and Living Death, and owner of the record label Aaarrg Music.

The first demos were recorded with the following line-up: Jochen Schroeder did not fit in and was soon replaced by Living Death guitarists Reiner Kelch and Frank Fricke.

Due to touring duties with his current band, Jörg Michael was replaced by Uli Kusch (using the name Patrick Duval) for the shortly thereafter following picture disc EP The Gnome.

Mekong Delta returned to the studio around new year 1987–1988, and recorded the concept album The Music of Erich Zann, with the same line-up, again produced by Hubert.

Fricke then left the band to focus on other musical styles, and the group decided not to replace him, as Baltrusch was able to play all guitar parts himself.

After recording this album, Jörg Michael left the band and was replaced by Swiss drummer Peter Haas.

Around this time, the self-imposed mystery surrounding the project was fading and in October 1991 they started touring parts of Europe, including the Netherlands and Germany.

Kaleidoscope, released in 1992, contains a cover version of "Dance on a Volcano" originally by prog-rock band Genesis.

At the end of 2005 Hubert was brought in contact with guitarist Peter Lake from Swedish metal band Theory in Practice and the project restarted.
