The web site of the Royal Opera House has an interesting feature on the Thein contrabass trombone it has recently acquired for Keith McNicholl.
"Some time ago, I became aware that I would be required to play a contrabass trombone in Wagner's Der Ring des Nibelungen opera cycle at the ROH. I was immediately excited at the prospect, but it soon dawned on me that my old Alexander contra wouldn't last five minutes in the orchestra pit - it is far too cumbersome and frail. After some discussion with the management it was agreed that the Royal Opera House should, ideally, own its own contrabass trombone."
