So after listening to the performance you posted, I found this short (6:59) video explanation about how a pedal steel guitar works, which I found very enlightening.
Steve Fishell explains how pedal steel guitar works.
The first steel guitar performance I ever heard was Santo & Johnny in 1959 playing Sleepwalk. I loved that tune and the sound of it.
I was only 9 then, but I got hold of the 45 and fell in love with the up-tempo flip side: All Night Diner.
The Steve Fishell link you posted is excellent for anyone on the thread who wants to get a VERY basic understanding of how one works.
The first one I ever heard was probably around 1962. Local C&W station was live-casting a local C&W band for a hardware store grand re-opening. I’d furiously pedaled my one-speed bike to the event (uphill both ways) because I’d heard they were giving away FREE sodas and hot-dogs, something nearly unimaginable to my 10 year old brain!
Yes, they DID have free sodas and dogs, but I’d never heard a live music band before in my entire life and was entranced with the performance, but most of all, I was just captivated by the steel guitar, which of course I had no idea what it was at the time, but when I excitedly described it to my parents, they told me it was a “steel guitar”.
I’ll never forget the scene: my first free sodas and dogs, my first LIVE C&W band, my first seeing a live radio broadcast, and my first steel guitar all rolled into one!
Thanks for the links; post.
