Setting up a poll such as this is rather like opening up a can of worms. The scope is so wide, and there are likely to be those holding widely differing opinions. For me there are also great differences between music I like playing and that which I like listening to. There are a number of pieces that are great to listen to, including some of the Eric Ball classics, which actually take an awful lot of playing, and you wonder whether all the effort is worthwhile.
I have selected Philip Wilby, as I feel he has given us a number of notable works, challenging for the players but approachable for listeners. Revelation and Dove Descending inparticular, when played well, can have a tremendous impact. As for other names, what about Ray Steadman Allen, Gilbert Vinter or Torsten Aagaard-Nilsen, not forgetting anyone who can write bass parts with sufficient interest and variety!
oh dear, how did Frank Bernaerts make the list!! I. To be fair he has done some good arrangements especially for youth and lower section bands, although I have known some bands to play too much of his music which can get a bit the same if you know what I mean! One moment in time must be one of his best arrangements tho.
All the above are great composers and help to make banding very enjoyable (most of the time) by the pieces they have written but I would like to make a mention of Darrol Barry.
I'm sure every band on here has at least one Darrol Barry piece in its library and they are always really good pieces with loads of interest for all instruments and always crowd pleasers. Remember 'A Salford Sinfonietta' anybody?
He's an excellent arranger and composer and one of the best qualities I feel he has is that he can write for all standards of bands.
Eric ball wrote some fantastic stuff to play. wrote GOOD BARITONE PARTS. Played Kensington Concerto (SOLO BARITONE) at Nationals last year off NUMBER 1 DRAW. Great piece to play But the number one composer for me would have to be GILBERT VINTNER: A composer who sadly died before he really got into writing for brassbands at any great length. If he had lived for longer just think what he would have produced for us to play. My favorite piece he wrote was ;JAMES COOK CIRCUMNAVIGATOR. My first British Open Contest was to hear JOHN O GAUNT i was only 4 yeares old and as the second band started playing it i said "NOT THIS PIECE AGAIN" so iwas taken around the ZOO for the rest of the day.:-D
