Los Dos En Gros, Tischhauser's extended exhibition, drums into the mangrove forest many times over – the rhythms disperse, disappear and never emerge from the quicksand holes. Unstoppable jungle drums aim for the dancing legs. The pyranhias hide trembling in the mud, the tapir family gallops into the undergrowth in search of shelter, the alligators lurk but don't move as the swamp blues rattle along. Only high up in the treetops do the tamarin monkeys dance and organise a wild scream to the driving beat of the octet. The hummingbird hums softly, the jaguar hunts deadly, the mamba sways to the mambo, the orang-utan wears a hat. The assembled silverbacks are cooking in old pots. It smells of gumbo, jambalaya, beans and rice. The Los Dos swamp and jungle blues anglo is slowly moving away from its roots and becoming a dance hall cracker, a riddim jam peppered with high-powered surf sounds and cotton riffs from the misty march plain to the Sihldelta down town Switzerlands, where the octopus wallows at the Platzspitz.
