MANILA, Philippines — Celebrating their 20th year in the music biz is American R&B group Boyz II Men. They commemorate this career milestone with the release of an aptly titled two-disc album “Twenty” that compiles their biggest hits and then some.

Considered by many R&B enthusiasts as one of the best vocal groups of their time, Boyz II Men is the quintessential singing group responsible for the resurgence of R&B music in the ’90s with smash hits “I’ll Make Love To You,” “On Bended Knee,” “Water Runs Dry,” “Four Seasons Of Loneliness,” “A Song For Mama,” and “End Of The Road.” Listening to these songs again, the words “vocal blending” and “soulful” come to mind. Boyz II Men rises above the usual parameters of a boyband, reminding us that they are an influential musical group as these recently re-recorded hits attest.

As for the new songs, the boys are still in great form. Original members Nathan Morris, Shawn Stockman and Wanya Morris still harmonize better than ever on new tracks like in the upbeat “Believe,” the lead single “More Than You’ll Ever Know,” and the slow to mid tempo ballads “I Shoulda Lied,” “One More Dance,” and “One Up For Love.” The last three songs see the three original members reuniting with hit slinging singer-songwriter-producer Kenny “Babyface” Edmonds for some new yet classic sounding Boyz II Men materials.

T-Pain returns with a lengthy album “Revolver” filled with his brand of vocal-processed R&B and hip hop.

Right out of the gate, in “Bang Bang Pow Pow,” T-Pain does what MCs like him do best, and that involves dropping lines about how good it is to be in this game, where “boatloads of cash” and “cars, money and whores” are de rigueur.

Moving on, T-Pain shows he’s good with the drum machine and synth combo in the bouncy “Bottlez” featuring Detail, and even better when going club-centric like in “It’s Not You (It’s Me)” featuring star MC Pitbull (also featuring R&B singer Chuckie).

T-Pain is up to his old tricks; still heavily into Antares or whatever vocal processing software he’s using. But unlike others who use auto-tune machines as a crutch, T-Pain uses it as a tool to get to the sound in his head. So whether going club like in “Turn All The Lights” or when switching gears with some slow grooving R&B stylings on “Sho-Time (Pleasure Thang)” or on the Chris Brown featured “Best Love Song,” you can be sure that T-Pain is “enhancing” the thing with his signature vocal processors.

The gadget-inclined rapper also recently clocked in the Billboard Hot 100 charts with a fetching little song called “5 O’Clock” featuring British singer-songwriter Lily Allen and rap and sophomore hip hop artist Wiz Khalifa.

“Revolver” also features Ne-Yo who appears in the club track “Turn All The Lights On” and R. Kelly on “Center Of The Stage.”

Is “Revolver” worth the while? Surprisingly, it grows on you and we won’t mind leaving this in the car to listen to every now and then.
