Coming from a musical family, Anu started singing rather than talking, according to her mother. In her teens, she sang in choirs in her hometown and played piano, saxophone and flute. Anu's musical expression is rooted in jazz. In 1999, she came to Belgium to study at the Royal Conservatory of Brussels, where she also formed her first band, called aNoo, which mixed jazz and folk influences in an original line-up with vocals, accordion and trombone. In 2007, she released her first album 'The Luckless Lands Of the North'. This was followed in 2011 by 'Sinipiika', which she made with producer Werner Pensaert (K's Choice, Clouseau, Jef Neve). But as the two albums she recorded with that band would prove, Anu was far from a jazz purist. The singer became more and more intrigued by samples and digital beats. This new fascination resulted in 'Skeletons' (2014), the first of her records on which she herself was at the helm. The EP 'Open Your Window' (2018) was produced by Koen Gisen (Dans Dans, Robbing Millions). In 2023, the fourth studio album 'Cometta' brought her closer to her roots. The musical material is now more stripped-down and austere, creating an intimate connection with the audience. 

The mix between Finnish heritage and Anu's Belgian experience gives her an instantly recognisable sound, a sound all her own. 'Komeetta' was recorded in Antwerp at the Caporal studio by Nicolas Rombouts, and the album was mixed and produced by Gil Mortio and Anu at the Marcel Delcourt studio in Brussels. Since 2011, Anu has also been co-leader of Brussels Vocal Project, a contemporary vocal collective that mainly performs newly composed material by collaborating with various singers and composers, including John Hollenbeck, Fabrizio Cassol and the Brussels Jazz Orchestra. Anu has performed on various stages and festivals at home and abroad. With her various projects, she has toured in Germany, Finland, Norway, China and Morocco. Anu is also a dedicated teacher and currently teaches at KASK & Conservatorium in Ghent and at the music academy of Jette. She is regularly invited to give workshops on jazz and folk singing.
