Vomit
History
Vomit were one of the pioneering thrash metal bands from Greece. Vomit was formed in 1985, but it didn't take long before they disbanded.
Vocalist Captain Death (aka Spyros of Varathron) found new members and Vomit came back in 1986. The band was influenced by Voivod (logo was very similar to Voivod's style) and old Celtic Frost.
9-track rehearsal demo 'Mechanic Abomination' was the band's first output.
This is where the signs end... Maybe other stuff was released, too?
