There's a new hip-hop collaboration coming to town with SISTAR's Hyorin, Block B's Zico and rapper PALOALTO!

Starship Entertainment stated, "SISTAR's Hyorin, Zico, and PALOALTO are currently preparing to release a special project at the end of this month. They're planning to show a hip-hop collaboration on a different 'class', so you can look forward to it."

It looks like the three were working together in secret for a new music release, but it's not a surprise anymore with this announcement!

As you know, Zico and PALOALTO make up one of the producer teams in 'SMTM4', so you know they have great teamwork, and we're excited to see how Hyorin will fit in.
