Hangaku lives on the thin line between music and noise. Their synth-based music is highly unconventional and sounds quite nervous. It's a bit like an electronic version of Melt Banana, turning chaos into structures and noise into a listenable combination of sounds. Yet, it's not easy-listening music, on the contrary.
Se Mustard Terrorists bring out the guitars and drums but still decide to play them in a quite unconventional way. This band rocks in a very entertaining lo-fi setting. Here too, the endresult is never noise but comes very, very close to it. It remains a highly experimental version of the White Stripes, and a lot better that the latter.
In all, this is an interesting split that will please many indie and underground fans but I don't think these bands will ever see the big audiences. That's ok by the way, this music is not suited for everyone. Only die-hard underground diggers will appreciate the awesomeness of this stuff and that's exactly how we like it...
