It's been over a decade since we've heard any new material from K-Ci & JoJo. The singing brothers return with a mid-tempo jam called 'Knock It Off.'

Over melodic guitars, cascading pianos and a bouncy beat, the brothers sing about their insatiable bedroom prowess.

"I'm lovin' your everything / I'll do anything to make you feel good / K-Ci's got that real good, real good," sings K-Ci. "And we can go all night / Wake up in the mornin' / And you'll be like it's still good, it's still good."

Despite the generic lyrics, the song is not that bad, plus, the brothers still sound really good.

The last time we saw K-Ci & JoJo, they were making the rounds on YouTube for their not-so great concert performances. But it appears the dynamic duo are gradually making a comeback.

K-Ci & JoJo are currently working on their currently untitled sixth album, which they plan to release in the fall on eOne Music.

It's good to hear K-Ci & JoJo are back in the studio again. We can't wait to hear what they are going to bring to the R&B game.
