As Esther's father is Crille Olsson (Fläskkvartetten) her childhood home was filled with musical instruments and she started playing at an early age. She started taking piano lessons at 6 and took up the drums a couple years later. She wasn't particularly obsessed with music but ended up going to a music school anyways, with classical percussion as her major. After playing classical music for the first couple of years, she decided to change tack to writing and performing her own music with vibraphone and vocals as her main instruments.
Esther has quickly become a true fixture in Stockholm's music community and has already collaborated on multiple recording sessions as a performer and co-writer.
