There was a time back in the spring of 2006 when young teens Dok2 and Microdot came onto the music scene with their debut album 'Chapter 1'. They were known as the duo All Black, and although short-lived (they only released that one album), they sure were talented.

Flash forward to over nine years later, and Dok2 is now a successful rapper, producer and co-CEO, and Microdot recently came back into the spotlight as a 'SMTM4' contestant.

And now both Dok2 and Microdot have announced on their SNS that they'll be making their comeback as a duo!

They posted photos of the two looking pretty cool together, with the announcement that they'll be releasing a new single "Goal Keeper", produced by Gonzo (Dok2).
