Postscript 2015: A very short post there and I see that you now have to pay 89p to hear the whole poem, although of course you can find it online: '...Untrodden parks and freezing underpasses. / The statuary anonymous, the cobbled chares / Like streams of blackened ice...' (Chares are narrow streets).
In 2009 The Guardian did a piece on Sean O'Brien which begins with a description of the landscape that inspired him:
'When Sean O'Brien talks about the north, he tells it like a story. His language, as he describes it, is tranquillised, rhapsodic; his voice drops; his sentences loop and lengthen. "I grew up in a northern city," he says, "and the landscape fascinates me: the flat, Saxon plains of east Yorkshire, the spectacular hills of the north and west, the uncompromising industrial cities - they form a complex identity. And they all touch on the Humber - the great, epic, Mississippianly wide river Humber - which runs past the doorstep like a continental division and moves out vastly into the sea. When we were kids, we used to think we could see palm trees on the other side."'
