Andrzej Piaseczny (born 6 January 1971) is a Polish pop singer. He was the leader of a pop-rock group M.A.F.I.A. in the 1990s. Later he released two solo albums under his stage name Piasek and debuted as actor in a soap opera. He represented Poland in the Eurovision Song Contest 2001. Currently he dropped his stage name altogether and prefers to be addressed by his real name. His current albums belong to the more old-fashioned poetic side of Polish pop music. The change of style was introduced with collaboration with Seweryn Krajewski.
