Both artists are tied to Boys Noize and I remember seeing ABRA in the studio with him on her instagram story at the same time that Gaga was, in a separate story posted on twitter. ABRA also recently followed Gaga on instagram. For most who don't know ABRA, shes a sort of darkwave meets R&B artist thats not too well known but is out there making a name for herself. She was featured on Charli's album Number 1 Angel as well.
