What a lineup. Any casual punter could readily be forgiven for being carried out in a box. Not that the sounds on offer were remotely toxic; on the contrary, they were entirely wholesome nut cutlets of crunchthudriffery, but seriously, heavy things can crush you, and things as heavy as this can crush you flat. Perhaps that’s why Colchester Arts Centre is ‘never knowingly understood’: stand under this sort of malarkey and you can wave goodbye to three-dimensionality.
