Mekong Delta is a thrash metal band from Germany. Taking their name from the geographic location of a massive massacre that took place during the Vietnam war, when about 4 million civilians were killed by US military forces. Mekong Delta pioneered the genre that is known as progressive thrash metal today, implementing strong melodical elements and classical concepts (usually based on Modest Petrovich Mussorgsky's pieces) into their thrash/speed metal sound, which became most prominent on their Kaleidoscope album. It is clear that the band is the key influence on modern technical progressive metal bands like Spiral Architect. Their newest album, titled "Lurking Fear", was released at 24.08.2007 after ten years of silence.

When the band first started, they were surrounded by a cloud of mystery, as all of the band members were under contracts with other bands, and thus had to use pseudonyms to avoid any legal problems.

The current line-up is:

Ralf Hubert - Bass
Uli Kusch - Drums (Masterplan, Helloween, Gamma Ray, Holy Moses, Roland Grapow)
Peter 'Lake' Sjöberg - Guitars (Theory in Practice, Mutant, Sorcery)
Leszek 'Leo' Szpigiel - Vocals (Wolf Spider, Scanner, Duke)

However, big names such as Jörg Michael (Drums, Rage, Stratovarius and Saxon) , Peter Haas (Drums, Krokus), Jochen Schröder (Guitar, Rage, Avenger), Frank Fricke (Guitar, Living Death, U.D.O.), Reiner Kelch (Guitar, Living Death), Uwe Baltrusch (Guitar, Sodom and PETER "PEAVY" WAGNER (Bass, Rage) have also been members of Mekong Delta at certain points.
