IMHO Sonorous is exactly right when he says "We have an astonishing set of highly talented individuals within bands, I would love to see some of them encouraged to branch out and take our hobby to another level. And in doing so inspire the rest of us to keep evolving and growing. It wouldn't happen easily, and it will always be down to some inspired individual (or set of people) to make a giant leap of faith."
This is exactly what James Shepherd Versatile Brass did in the 70's , and they pulled fabulous audiences for years and years.
New music was produced, Concert presentation was different and the groups popularity took them from RAH to Australia and back .I know it wasn't easy for them , especially early on, and all the members had to pay subs ( even James Shepherd ) which helped hire a rehearsal room etc., but their perseverance and hard work was worth it. So , banders, please heed Sonorous and do something.
