The gold connoisseur has seen it all: white gold, green gold, black gold, even fool's gold. But, there's another kind of gold out there, "Blues Gold."

That's right, blues music gold. I'm referring to some of the greatest blues masterpieces of all time, like "Call It Stormy Monday" by T-Bone Walker; "Have You Ever Loved A Woman" by Freddie King; and "Hound Dog" by Big Mama Thornton.

These and 35 other classics dating back to 1947 appear on the new compilation album Blues Gold. There's Delta blues, Chicago blues, rhythm-and-blues, and acoustic blues performed by Eric Clapton and Duane Allman.

Eric Clapton and Duane Allman showed their appreciation for the blues on this 1970 recording, "Mean Old World."

For country blues fans there's singer and guitarist Kevin Moore, better known as Keb' Mo'.

Keb' Mo' is a modern blues giant, literally. Keb' stands almost two meters tall, with or without his guitar.

Where there's Blues Gold there's electric blues gold.

Who could forget the opening scene to Terminator 2: Judgment Day, as a completely naked Arnold Schwarzenegger walks into a bar to a 1982 blues-rocker song?

It's not unusual in blues to be linked mainly to one big blues hit: Koko Taylor to "Wang Dang Doodle," Guitar Slim to "The Things That I Used To Do," and George Thorogood and The Destroyers to "Bad To The Bone."

Long live the new generation of blues men and women, represented on Blues Gold by rising stars Susan Tedeschi and Jonny Lang.
