I'm sure you all have an idea of what today's recording studios look like, and pretty much how they work.
Cables everywhere, lights flashing, computer screens, huge mixing desk with more nobs than a New Zealand First party conference...
Not at all how it was seventy years ago -- and how much technology has progressed since then!
Have a wee look at this video at You Tube to see what early electrical recording was like -- and this was an advance on the bellowing into a tube that was happening only ten years before -- and you can also get a glimpse of the great Duke Ellington and his band in the studio with singer Ivie Anderson.
It's amazing that anything from 1937 was recorded at all, and delightful that it was and we can still enjoy it today.
