On the heels of the release of their 20th anniversary album 'Twenty,' Boyz II Men have dropped a visual for their lead single, 'More Than You'll Ever Know.'

The video, which was directed by Corbin Thomas, Joe Mulvihill and Lunchbox, features Gap Band singer Charlie Wilson, and includes performance footage of the group rocking poolside with the R&B legend at an L.A. mansion in the hills, overlooking the city, coupled with shots from the studio, with the foursome laughing, goofing around and recording.

Check out the video after the jump. Boyz II Men, whose 'Twenty' LP is in stores now, recently spoke to The BoomBox about their storied career. Read the exclusive interview here.
