Kenny G

[efunk_adelic]

What was Kenny G's first appearance in a group at the tender age of 17 from the 70's?

[K-Bee]

That would be Love Unlimited Orchestra.

However, Gorelick also formed two different groups even before LUO with fellow High School student Phillip Woo (who later was to be involved with Roy Ayers and Maze)
The group names were "Energy And Cold" & "Bold & Together" but I doubt they ever recorded anything.
