Tic Tac Toe

Tic Tac Toe was an all-female German group. Formed in 1995 in Ruhr, they released their self-titled debut album in 1996. Their second album, Klappe die 2te, was released the following year to even a greater success. After a successful first few years, the group split due to personal difficulties in 2000, having sold over 3 million records. Tic Tac Toe attempted a return to the spotlight by releasing a hit single "Spiegel" in 2005. After disappointing sales of their 2006 Comeback album, the Tic Tac Toe project was abandoned.
