Hey are a well-known Polish rock group from Szczecin. Their leader is Katarzyna Nosowska who is also a successful solo artist. The high point of their career was somewhere between 1993-1995, their debut album selling 200,000 copies. If you know anything about Polish music, you'll know her song 'Moja i twoja nadzieja' (My and your hope) a popular tune during the big floods in 1997. There are plans for a new album in 2012, so we might hear some tracks from it here.
