I think that it is hard to determine a individual greatest brass band composer because they are all good in diffrent ways and because there are so many!e.g Philip Sparke, Peter Graham, George LLoyd,Eric Ball,Herbert Howells, Percy Fletcher,etc
but i think my overall favourite would have to be...
Who do you think that the best current euphonium player is at the moment?
I think that it is currently between three players!
these are in no particular order!
David Thornton Black Dyke
Morgan Griffiths Faireys
Glyn Williams Fodens
This is just my opinion let me know wat u think!
