Drip... drip... drip...
Here, deep beneath the Northern Line platforms at London Bridge station, the four grey water from London's melting snow gathers in fetid stinking stagnant pools.
But there is light at the end of the tunnel. And a gentle aroma of freshly brewed Italian coffee.
Follow the light...
Down through the claustrophobic labyrinth of rotten Victorian tunnels...
And there you find Skymind in the warm glow of his laboratory.
He turns, smiles and presents you with "From up here 15" an eerie mix of mellow melancholia from the world of electronica and beyond.
Quite why he's wearing sunglasses, in February, underground - your guess is as good as ours!
