Mic No.

9 is definitely a special mic.

It's a RCA 77DX, that's the model.

It was made around 1950.

And, during those days, everything was handmade.

So, we have four identical mics, so that when we lined them up and there's something uniquely magical.

Like, they all sound similar, but microphone 9 just, I don't know.

It sounds like whovever made it wa s having a real good day and he put that good energy into the mic.

[Al Green's "Let's Stay Together] Now, I've had the pleasure of recording Al Green as well, which it was a unique experience because I've never seen anybody have that much control over their vocal.

The first time I recorded Al Green, we put him on the mic.

The mic is here and he starts walking over here but still singing, but it sounds like his voice is right there still.

I stood up to say something and my dad goes, "No man, just be cool."

And, he's such a master of his voice.

He can literally walk around the room and make it sound like he's right in front of the mic.

And, those records, they still, they just, they sound different, and they're just, I don't know.

They sound like pure magic to me.

[Ann Peeble's singing "I Can't Stand the Rain"] Memphis soul music over the years has had a very strong impact on the African-American community.

Just for example, when, when STAX closed in 1975, they were the second largest employer of African-Americans in the country, next to Ebony and Jet magazine.

So, you had a huge income stream and wealth was created from STAX, from here.

I mean, Al Green had six consective number one, platinum-selling albums.

Al Green was one of the first African-Americans to sell millions of albums.

He was also one of the first African-Americans to sell out arenas.

So, when other R&B artists or soul artists like Aretha or Ray Charles, they're playing theatres like The Orpheum.

Al Green was playing wherever The Stones played, like arenas.

So, there was a huge amount of, honestly, generational wealth created from soul music, from Booker T. Booker T left Memphis and went and produced all those wonderful Bill Whithers records that we love.

And, you know, there's so many branches of the Memphis soul sound that have, you know, just created legacy, wealth.

If I was stranded on a desert island and had to take one soul record, it would be Al Green's Greatest Hits.

There's a family connection there, but it's, I don't know, to me it's one of the most iconic records of all time.
