Kassimou Djae, also known as Segnor Alonzo or simply Alonzo, is a rapper and singer who had major success as a member of the chart-topping Marseilles-based rap group Psy 4 de la Rime. He released three albums with the group, then went solo. He debuted with the 2009 mixtape Un Dernier Coup d'Oeil Dans le Rétroviseur, prior to releasing two albums on Def Jam France: 2010's Les Temps Modernes and 2012's Amour, Gloire Cité. Both sets reached the Top Ten of France's album chart and confirmed Alonzo's status as one of the country's most popular and respected artists.

Two albums from 2015 became Top Five hits in France: first came Règlement de Comptes, led by the Top Ten single "Même Tarif" featuring Booba, and later in the year he released Capo del Capi, Vol. 1 with the single "Normal" featuring Jul. In 2016, Alonzo returned a favor by featuring on Jul's hit "Ils le Savent." He also released Avenue de St-Antoine, his first number one album in France. ~ Andy Kellman, Rovi
