Acid Death have anchored Greek extreme metal since 1989, and this Kyttaro night doubles as their first official live album: recorded on the spot from a set that reaches across all eight of their records. It also marks 37 years of a band that turned progressive death metal into a Greek staple. Kikabass Productions fills out the bill: Null'o'zero and their Heavy/Power/Thrash, the death, black and thrash of Athens' Karma Violens, going since 2002, and Gunsmith, an Athens death metal crew currently tracking their debut EP. Four bands, one recording.
