Their first project together - the Musical Marathon Ensemble - was inspired by their great love of musical theathre. In the spring of 2017 they joined forces with the pianist Éva Bárkányi-Horváth and the three artists formed the SightSingers Ensemble. Their debut concert took place on June 19, 2017 at the K11 Cultural Center in front of a sold-out hall.

Hanna and Anita have known each other since 2003. Their friendship started when they were both studying violin and voice at the King St. Steven Conservatory and Music School. In the class of Judit Adrigán they learnt varying musical styles including opera, operetta, chanson, couplée and musicals.
