After opening with a performance of “Feel It (In The Air Tonight)” — their riff on Phil Collins’ classic that was almost identical to the one we posted here last week — one of the members of Naturally 7 welcomed the audience to the show.

For the uninitiated, Naturally 7 mimics the sound of musical instruments with their voices. That, along with their supertight harmonies, is what creates their unique style.

Anyway, Rod Eldridge paused to tell the audience, “Hello Memphis! We see you being all prim and proper. Relax and have a good time. Also, we notice y’all being all polite. You put away your cell phones so you can’t shoot video . . . but we like it! So go ahead and shoot pictures, take video . . . just tag us on Facebook when you post it!”

So . . .  Here’s “Wall of Sound:”

And I don’t know the name of this gospel-flavored reggae medley, but it doesn’t matter. These guys are AWESOME!
