Henry Koek and Arnold Cabott begin their collaboration in 2013. They create a trio, Nos Namajs, with André Darius, record for Netlabel, and play live. Henry and Arnold meet Rachel in a gig, in Marseille. She plays with Heard of Bears (Francois Wong, Ed Williams, Rachel Chen). There was a jam session. Then Miss Chen leaves to Singapore.
In 2015, Rachel came back for a short time in Aix en Provence. In July, Rachel, Henry, and Arnold play together, an afternoon in Aups and record this album - RHA.
