I've seen this complaint/compliment throw around regarding this band: they sound too much like (insert band name here) from the 70's, or such-and-such horror soundtrack, etc. Certainly, this group Zombi is nothing astoundingly original, but their sound is a loving and exacting tribute, if nothing else, to the most creative and inspired music of the 70's and even 80's.
The band consists of two musicians (I won't go into names or minute details), who between the two of them play synthesizers, bass guitar and drums. As far as comparisons goes, this music is most similar to many current groups which were most prolific and interesting in their heyday: Tangerine Dream, Rush, Genesis, and others. One of the groups biggest influences, however, is the Italian group Goblin, who most famously created soundtracks for directors Dario Argento and George Romero (Zombi is the Italian name for the classic movie/soundtrack Dawn of the Dead).
I hate to critique music these days, but I want to end with this: it's nothing that will shake the foundations of the world, but Zombi's music is exciting, adventurous, and fun. The drums are amongst the best I've heard in my rather brief but music-absorbed life, and the synthesizers are pure vintage 70's Moog and likewise. Tracks 2 & 3 are my favorites - they have simple, synth & sequencer driven riffs with tons of layering and interplay from the drums and bass. The rhythms are rather static, but they build up to incredible heights. It's hard to describe, as you can see, but the results are fantastic. Check it out!
