Treading the fine line between the sane and the insane, jazz metal confusionists Ephel Duath present their latest affront to common decency with the mind-melting paradigm that is 'Pain Necessary To Know'. Relying more than ever on a duplicitous jazz backbone to set against the raw extreme Metal argument. The band comes across as the bastard offspring of Primus, Mr Bungle and the Dillinger Escape Plan, set against a non-conformist background of Zorn-Influenced paranoia. Revel in the intentional discomfort.
