Hey has anybody heard of Marc Dickman? He's got some great jazz stuff. His album is called weaver of dreams. He's got some great music on there. I highly recomend it.
Oh, yes, we have. Just do a search for "dickman" on the forum. You will find posts like this one, where you can hear him play:
Marc Dickman MP3
And you'll find him and other jazz euphonium players here:
And if you do a search for his last name on my main site you'll find dozens of listings. He's a fine player and teacher.
If guys like this keep forcing the issue, then I think there will eventually be more performance venues for the euphonium. The Big Band thing is cool!
