My day job is as a dock worker which involves operating some heavy machinery to allow boats of all sizes in and out. These machines make some cool sounds, so I recorded some of them.
'Bridgelift Blue' was recorded with a Rode nt4 from inside a single-leaf bascule bridge, 'Without Warning' was recorded with a pair of DPA 4060s dangled down into the inner body of one of the sluices of the lock. Both recordings have been substantially abridged.
