I admit, it's kind of strange to describe math rock tracks as 'jams'. The word 'jam' implies that a bunch of muso's can pick up instruments and follow along to a common pulse of sound. The dissonant nature of math rock surely makes this simple affair rather awkward and complex, maybe even impossible.
Even in this digital age where you can find about any genre under the sun, it's hard to find a band as eclectic and bizarre as Nojikas. Still, from a listen to this latest frenetic release the バレエ Ballet Mechanic EP, it's clear that this Japanese experimental outfit couldn't really exist in any other time.
