Shawn Stockman of Boyz II Men discusses their sold-out concert in Delaware on Friday.

Boyz II Men will display their harmonizing prowess at Dover Downs Hotel & Casino Friday, in a concert that’s been sold out for weeks.

“We are so excited to play for the fans of Dover! It is such an honor to have a sold-out show and we can’t wait,” said Shawn Stockman, the group’s slim, tenor singer. “We have performed in Delaware a number of times and we always love the fans and energy there.”

Stockman and his melodic partners – Nathan Morris and Wanya Morris – are in their 21st year as a group. Boyz II Men holds the distinction of being the best-selling R&B group of all time. They’ve sold an astounding 60 million albums. That success revolves around their rich catalog of hits, filled with smooth harmonies and enduring themes.

Some of those timeless tunes include “End of the Road,” “I’ll Make Love to You,” “One Sweet Day” and “Motownphilly,” among many others.

Those two decades have been eventful, to say the least, for the group. They’ve won four Grammy Awards, nine American Music Awards, nine Soul Train Awards, three Billboard Awards and a 2011 MOBO (Music of Black Origin) Award for Outstanding Contribution to Music.

Their knack for winning has also been coupled with loss as bass singer Michael McCary left the group in 2003, shrinking Boyz II Men from a quartet to a trio.

Stockman dished on Boyz II Men’s new album, being a judge on NBC’s “The Sing-Off” and why McCary was never replaced.

Tell us about Boyz II Men’s new album.

The doo-wop album has been a lot of fun to work on. We have been able to collaborate with some amazingly talented artists and the fans won’t be disappointed.

How did the idea of a doo-wop album come about?

We have always been influenced by doo-wop music, so we wanted to pay tribute to it. Fans will be able to get the album in 2017. 

What attracted you to “The Sing-Off?”

I love discovering new talent and seeing what is out there. I have been developing “The Dame Sound” for a few years and it has been such a rewarding experience. “The Sing-Off” has been a fun show to work on and I got to meet some incredibly talented artists.

I have really enjoyed being a part of the show. Seeing groups like Pentatonix go from “The Sing-Off” stage to touring internationally has been so rewarding and I love being a part of their journey.

Since parting ways with Michael, had the group considered bringing in a replacement?

Nate is extremely talented and has an incredible vocal range. When we parted ways with Michael, Nate was able to jump into that role, so we never needed to consider bringing someone else in.

R&B is almost non-existent these days. If you could do something to revive it, what would that be?

As a group – Nate, Wanya and I continue to perform and remind the fans why they love R&B. We are still able to play to a sold-out audience at our residency at The Mirage in Las Vegas. So while artists may not be creating traditional R&B music, the fans still appreciate it and love seeing it performed.
