Orthros

Orthros formed in Athens in 1997, taking their name from the three-headed dog of Greek myth. They started with a sound that mixed progressive metal with hardcore punk and thrash, which could be divisive at their early live shows. The band's lineup has shifted some, but vocalist and guitarist George Emmanuel and drummer George Kollias have been constants.

Their 2005 album 'Alpha and Omega' was a turning point, pulling together their approach into something that clicked. They've put out nine albums in total, including later ones like 'Apokalypsis' and 'The Devil's Rage'. Their lyrics often deal with dark, existential themes, which has sparked some debate among listeners about whether they're nihilistic or just honest.

They've worked with a few notable musicians over time, like former Sepultura vocalist Derrick Green and guitarist Gus G. Songs like 'Alpha And Omega' and 'Walking By The Moonlight' give a sense of their style, intense, technically sharp, and unflinching in its mood.
