They're moving from their typical venue to the "civic auditorium" because they'll be showing accompanying videos.
I'd predict a bunch of ticket sales, per typical John Williams' pops.
I'm covering the 4th trombone part on F cimbasso and then moving to tuba on this piece (as well as playing F tuba on "Jaws" - so three (count 'em) THREE *apparati.
(In a past concert, I did the same thing on "Summon The Heroes"...actually, when I came up with my "Shallowberger" mouthpiece, as the 4th trombone parts in this Williams pieces - up to F or G, etc. - are just too much unnecessary effort (playable, but more work than necessary, and - truth be told - less focus) with a typical "F tuba" mouthpiece.)
...so I'm playing cimbasso through 85, and then switching to tuba to finish it out.
There's a section (4th trombone part - maybe around m. 121 and onward...?? - page 2 in both parts) where the 3rd and 4th trombone parts clash in semitones (which seems important to me), but the maestro tells me the same clashing pitches are covered in a couple of other parts, and to just stay on tuba and hit the buttons in the tuba part...OK...fine with me.
comment: It's fun - occasionally - to be able to cover to cover the MELODY (particularly a WELL-KNOWN and fun melody) to a piece of orchestral music.
