Naturally...

I'd heard of this group a long time ago through a friend but couldn't remember their name...now all is revealed! Naturally Seven is their group name and they are seven men of exceptional talent. Evolved from acapella into what they dub a vocal band, they create instruments with sound of their voices. Hear it and you won't believe that it is all them. Like I said, exceptional. Of course it helps that they are also incredibly suave.
