Eicher's success started in German-speaking countries in the 1980s when, as part of the band Grauzone, he had a hit single, Eisbär.

With hit songs such as Combien de Temps and Oh Ironie, his popularity spread across Europe with albums, tours and chart success in France and Switzerland.

He became interested in French songs by Jacques Dutronc, Georges Brassens and Serge Gainsbourg, and these influences led to the album Les Chansons bleues.

This album is also inspired by the American singers he listened to during his youth, such as Patti Smith, Johnny Cash and Bob Dylan.

Following a world tour, which included concerts in Africa, he produced his first live album in 1994 (Non ci badar, guarda e passa).
