What on earth is that? A guitar that sounds as if Metallica's Sandman is creeping round the corner; over it a first cautious but ever increasing big-band wind set, with grooving drums and rock guitar intervening.

Jazz sensitivity and hard cutting rock interchange in the last six minutes of the track "Tantalos".

And continually reassemble. In the album "TANTALOS", Kuhn Fu, based around the guitarist Christian Kühn, still sits, where the ensemble has no doubt felt most comfortable since 2012, between all stools.

This applies not only to the entire jazz-rock complex - for rock music too much jazz, for jazz too much rock - but also to the consistent rebuttal of a pallid musical seriousness.

Big-band, hard rock, metal, punk and symphonic music are central (and equal) inputs. In case of doubt, Kühn's compositions turn to humour.
