Tau (rapper)

Piotr Kowalczyk (Polish pronunciation: [ˈpjɔtr kɔˈvalt͡ʂɨk]) (born 25 June 1986), better known under his stage name Tau ([ˈtaw]), and formerly as Medium ([mɛdium]), is a Polish rapper, singer and record producer. In 2008, he released his underground debut album Seans spirytystyczny (Séance) under the name Medium.
