It’s been four years since Pittsburgh synth-prog duo ZOMBI has dropped original material. After re-releasing “The Zombi Anthology” earlier this year, Steve Moore and A.E. Paterra make up for the long wait not only with a brand new studio album, but Moore’s freaky good retro soundtrack for the Belgian horror film “Cub”. Moore’s synth-bound, creepy score for the film, which is about Cub Scouts victimized by an unhinged poacher on a camping trip, will remind veteran horror junkies of John Carpenter/Alan Howarth and Lucio Fulci. No surprises there, but Moore’s near-flawless emulation on “Cub” is startling, even with his pedigree.
