The song was the first artistic collaboration between Cremoni and Ayane, who were in a relationship at the time.[2][3] The orchestral arrangements by the London Session Orchestra conducted by Nick Ingman.[4] It has achieved good radio success. In an interview with Rockol Cremonini explained the meaning of thes song and the decision to collaborate with Ayane:[5]
"Malika asked me for a song for her album, so I wrote her "Believe in love" which went into Grovigli. It then happens that whenever you do collaborations a give-and-take relationship arises, and 'Hello' kind of completes our artistic encounter. Malika has an extraordinary voice, she has a voice that opens the clouds and has an extraordinary effect on human beings: put into one of my songs is an extraordinary gift."
