Bass handbell ensemble music hasn’t been doing a lot of growth since Low Ding Zone decided to head off into the sunset. Come to think of it, LDZ might have been the only source of music of that sort for most of its existence.
Anyway, one piece that LDZ might have played, but certainly never managed to record, is Go Tell It on the Mountain. Fortunately, the Seattle Bass Handbell Ensemble made a great video of it on 2009!
