Literature selections are subjective to the groups strengths and weaknesses and are chosen from the following two lists.
I have taught pieces from both lists and use this as my go to resource.
The first two lists are a collaborative google spreadsheet shared with numerous band directors across the country. It updates in real time, so that new arrangements may be added and we all can support each other as we lead our groups towards playing great literature.
The second list is from the Tennessee Bandmasters Concert Band Festival List.
