Starring: After 5Director: Kiko MeilyThe official music video of “Pers Lab” by After 5. All female sing and dance group After 5 have proven themselves more than just young pretty faces. After a couple of singles and one of the main drivers of The PPop Generation, After 5 -- Anne, Rachel, Karla and Andrea -- are moving up from teen-dream talents to legit pop group with substance. And its evident here on their latest single "Pers Lab." After 5's tight harmonies and execution give this Hotdog classic the nod it deserves and more. Their fine cover makes it on the "Para Sa Broken Hearted' album OST.
