PROBEAT Entertainment dropped an MV teaser for 4-member girl group SOL-T whose goal seems to be taking on the 'girl crush' title with their edgy concept.  They show off their dance moves and make movements that reference baseball as appropriate for their title, "Curveball," which can translate directly to a question that is very straightforward and abrupt, usually taking somebody aback.

Listen above!  The sound seems promising so far.
