Symphonia opus 21, fanfare-orchestra, played by the Frysk Fanfare Orchestra on the World Music Contest of 1991:

St. Caecilia, Januari, 1992, Frans Stoks:
The enjoyment of the concert began with the Symphonia opus 21 by Marc van Delft. The sound has something visionary, it reminds us of great, inhospitable landscapes, loneliness, but without desperation.

St. Caecilia, June 1992, Cunéra van Lier:

‘The composition Symphonia has left me with deep admiration for the composer.’ ‘The music was very imaginative.’ ‘Marc van Delft knows how to make a fanfare orchestra sound exuberant, with help of a very intelligent use of instrumentation.’ ‘Very beautiful music which deservices a place in the repertoire of the fanfare orchestras.’
