Petra Linnea Paula Marklund better known as September (born in Stockholm, Sweden on 12 September 1984) is a Swedish dance singer. Her mother is Slovenian and has a musical past and her Swedish father is a professor in space physics. She started recording music in studios at the age of 12. When she was 17, she sang in a rock band and gained a record deal. The songs were written and produced by Jonas von der Burg, Niclas von der Burg and Anoo Bhagavan. In 2003, at the age of 18, she had her first hit in Sweden with La La La (Never Give It Up), which reached number eight in her homeland. The single was followed by We Can Do It, which became her second top ten hit. As a result of these two singles, her debut album was recorded and released in February 2004, along with the third single from the album, September All Over, which reached the number eight position as well. It then stayed quiet for September until she broke the silence by releasing Satellites, as the first single from her second album In Orbit, which became her biggest hit to date. The song currently stands at number 139 in the Swedish All-time Bestperforming Singles Chart. Other singles that followed from the same album included Looking For Love, Flowers on the grave, Cry For You (which can now be considered her biggest worldwide hit to date). In Poland September's second album, In Orbit, was released with new remixes and a DVD with music videos from the album. The album was well received there and peaked at number ten for two weeks, being certified Gold by selling over 10,000 copies.
