The track 'Severnya' has a selection of samples from an old Russian film, title unknown, and I don't speak Russian, so I can't translate it. I seem to remember the film involved some monks on a journey somewhere, looking for something. But I could be wrong . . .

'Krakatoa' and 'Kinaesthesia' both get there vocal samples courtesy of a natural history series from the late 1980's. The 'Krakatoa' sample was part of a programme about volcanoes and such like, and 'Kinaesthesia' got it's sample from another programme in the series about extreme weather conditions.
Krakatoa
Another catastrophic eruption had taken place on the tiny island of Krakatoa, on the straits between Java to the east and Sumatra to the west. And in 1883, it was an island 5 miles long and 3 miles wide, with 3 volcanic peaks on it, the highest of which rose to almost three thousand feet. But those peaks were dormant, there had been no sign of any volcanic activity on Krakatoa within living memory. But then, in August of that year, people on the coast of Java began to hear a series of explosions. A great column of smoke rose above Krakatoa. Pieces of lava the size of a house were being thrown high into the air. The explosions continued, day after day. The column of smoke rose up until it was 5 miles or so, up into the sky. Ships that were sailing nearby had their decks covered in ash and pumice, and at night, electric flames played over the rigging. Day after day this continued. And as it was doing so, it was emptying the lava chamber deep in the earth's crust beneath the sea. And that was the cause of the greatest catastrophe of all. Because on the morning of August 27th, Monday, at 10 o'clock, the roof of that lava chamber collapsed. Millions of tons of sea water poured onto the red hot lava, so did millions of tons of rocks. And this produced a titanic explosion. The noise was almost certainly the loudest noise that has ever echoed round the earth in recorded history. It was heard two thousand miles away in Australia. Three thousand miles away, on the small island of Rodriguez in the south Atlantic, the commander of a garrison heard it, and thought it was the sound of distant gunfire, at sea. The explosion also produced a tempest of wind, which swept out entirely round the globe seven and a half times before it finally died away. But most catastrophic of all, the explosion produced a tidal wave. It swept towards the coasts, and as it approached, it became a wall of water over 100 feet high. It crashed into the harbours of the little villages, it picked up a naval gunboat with a crew of 28, and lifted it bodily for over a mile inland, and dumped it, on the top of a hill. And it overwhelmed village after village. Over 36,000 people were killed. The pall of ash brought darkness over an area of a hundred miles or so for several days. But when it cleared away, they found that the island of Krakatoa was unrecognisable. Three quarters of the main island had dissappeared. The 2 nearby islelets were buried beneath massive deposits of ash. And where the tallest peak had stood, the sea was nine hundred feet deep. But not for long. Forty-four years later, another island rose from the boiling sea. They called it Anak-Krakatoa, the child of Krakatoa. Compared with the explosions of it's parent, it's eruptions are still trivial bubblings.
