In 1994, Brown, along with Mel C, Geri Halliwell, and Victoria Beckham responded to an advertisement in The Stage magazine. Around 400 women who answered the advertisement attended auditions at Danceworks Studios in Mayfair, London. Halliwell, Chisholm, Beckham and Brown were originally chosen as the members of the group, and then formed a quintet with Emma Bunton. The group felt insecure about the lack of a contract and were frustrated by the direction in which Heart Management was going and broke with them. In 1995, they toured record labels in London and Los Angeles and finally signed a deal with Virgin Records. Their debut album, Spice, was a huge worldwide commercial success, peaked at number one in more than 17 countries, and was certified multi-platinum in 27 countries. The album centred on the idea of Girl Power, and was compared to Beatlemania. In total the album sold 30 million copies worldwide and became the biggest-selling album in music history by a girl group and one of the most successful albums of all time. The first single, "Wannabe", reached number one in 37 countries and all the following singles – "Say You'll Be There", "2 Become 1", "Who Do You Think You Are" and "Mama" – also peaked at number one in United Kingdom.
