Gaston ("Gast") Waltzing (born 1956) is a Luxembourg trumpeter and composer. He has created several jazz bands including Largo and the Luxembourg National Jazz Orchestra and has composed music for films and television programmes as well as operas combining classical music with jazz and rock.
Born in Luxembourg City on 13 August 1956, Waltzing began his music studies at the Luxembourg Conservatory when he was just 7. He continued his classical training at the Royal Conservatory of Brussels, completing his studies at the Paris Conservatory.
In 1982, he became Professor of Trumpet at the Luxembourg Conservatory and in 1986 he founded the school's Jazz Department which he heads. He has recorded numerous albums covering classical, jazz and dance, with groups such as "Atmosphere", "Life's Circle" "Largo", all of which he created himself. As a composer, he has recorded music for the Luxembourg film A Wop Bop A Lop Bop (1989), as well as for television. The TV film The Way to Dusty Death provided an opportunity for him to compose his first orchestral movie score. Since then, he has continued to write for orchestra and has worked closely with the Luxembourg Philharmonic Orchestra for which he has conducted the "Pops At The Phil" programmes featuring singers such as Dionne Warwick, Maurane and James Morrison. All in all, he has written over 150 scores for television and movies.
In 2004, he founded WPR Records which sets out to promote young musicians and has featured the Luxembourg National Jazz Orchestra. In 2008, Waltzing was appointed jazz director at the Echternach International Music Festival.
