The album begins with the title track (Blossom) a light and immediate song composed by Besson. Also composed by Besson are 'Kyoto dans la brume', inspired by a stay in Japan's imperial city, and 'La Course', originally written for three slapstick short films by Fatty Arbuckle starring Buster Keaton. Suarez's composition ' Sans laisser d'adresse' , was initially written for a stage play titled ' Ici Nougaro' , and his ' Le jour J a l'heure H' for a film by director Jean- Henri Meunier. 'Les Tuiles Bleues' is a nod to Suarez's late friend, Malagasy accordionist and singer, Regis Gizavo.

There are also three covers on the album, 'Answer Me' by Gerhard Winkler and Fred Rauch, a composition recorded by Keith Jarrett during his 2016 European tour; Besson cites Jarrett as a major influence. There is also Carla Bley's ' Ida Lupino' and Pat Metheny and Lyle Mays' ' Au Lait'. These and their own compositions result is Blossom' ', a highly accomplished album on which trumpet and accordion shine in equal measure.
