Born in the Grand Duche of Luxembourg in 1956, Gast Waltzing's defining passion has always been music. At the age of 7 he began his studies at the Conservatoire of Luxembourg, continued his classical training at the Conservatoire Royal de Brussels and completed his studies at the Conservatoire National Superior de Paris. "I am always a musician" he states, "It's not like I wake up and decide where to schedule music in. It is always present." He was named Professor of Trumpet at the Conservatoire of Luxembourg in 1982, and in 1986 founded the Jazz Department of which he remains the head.
