After a bit of a career break, Recording of the Week returns to the Sound and Vision blog! Every fortnight we'll be shining the spotlight on some of our most treasured recordings, from poets to politics and everything in between. Specially selected by experts from across the sound archive, these recordings will offer tantalising glimpses into a much larger collection of over six million items. 

We'll be keeping these selections short and sweet so, without further ado, let's kick off the new season with some singing steel, courtesy of National Life Stories interviewer Paul Merchant.

Metallurgist Sir Harry Bhadeshia tells the story of a steel that cried out. Its crystals sang as they formed themselves into the shapes that make 'Super Bainite' the strongest armour in the world.
