Laubier first came to prominence as one of the main producers of French rap group TTC, and was responsible for producing their 2004 signature tune Dans Le Club. With fellow TTC producer Tacteel he made up the now defunct live/improvised electro outfit Fuck-A-Loop (whose only recorded material prior to 2007′s nine hour digital album The Early Aughties was a 2006 remix of Ellen Allien’s Down). In 2007, he remixed The Prime Time of Your Life by French house duo Daft Punk. In 2008, Para One got his biggest commercial hit by remixing #1-hit song Greatful Days by Japanese popstar Ayumi Hamasaki. This song was released on the album Ayu-mi-x 6: Gold.
He also produced the soundtrack of the film Water Lilies directed by Céline Sciamma in 2007. In 2011, the song “Always” from his and Tacteel’s Fair Enough EP was featured in the same director’s film Tomboy.
