Laurenţiu Mocanu, better known by his stage name Guess Who is a Romanian rapper. He began his career as a member of the rap group Anonim along with group members Zekko and Griffo, and later launched a successful solo career in music. He is one of the most successful artists from the new wave of Romanian hip hop and has gained considerable appreciation and mainstream attention in his native Romania following the release of his first solo album in 2009 called Probe Audio. Guess Who gained popularity as a solo artist in 2007 when he leaked three tracks he had recorded for his solo album on the Internet. The feedback was overwhelmingly positive and his cynical and ironic approach to writing quickly earned him a large fanbase. Even though he repeatedly delayed for over two years releasing his first album, the Romanian audience received it well and he even gained attention from high level Romanian music executives when his video for the first single Tu was aired on the Romanian music channel 1Music.
