The first church you linked is supposed to be a pretty big deal, but that performance (well...) sounded sorta lame (inaccurate and rushed).
Obviously (with any gig) "who's available" varies from year-to-year.
The brass players in the second one you linked sound better, but not enough organ...and too boomy (recorded from too far away, maybe...?)
Our principal trumpet lady is a doesn't-miss player...The young man playing second is as well, and is headed off to IU, next fall.
I would critique my playing as "fine" at 9 A.M...but I wasn't totally awake.
I would critique my playing as "exceptionally good" at 11 A.M...I'm NOT an early morning person...and even 9 A.M. is still slightly fuzzy for me.
(CALL me at 9:00, but please don't show up - at blokeplace - until 10:00 or later.)
I fell like (when more awake) the tuning is better, and the resonance (euphonium) on my really low range (E-flat down to C) is better...At least, it FEELS better.
Those Richard Webster arrangements (there are quite a few of them) are Anglican-oriented, were actually written for a larger ensemble than a quintet (but bass trombone on the bottom - no tuba), but are frequently adapted for five players. A Memphis suburban BAPTIST church (quite a few years ago, shortly after building their sanctuary, and moving their services out of their gym) brought Dick Webster down to conduct a bunch of his brass/organ/choir arrangements. I was actually doubling on bass trombone (back then) practicing a lot, and sounded quite good playing it (a dependent-system Yamaha that I restored). DIck kept telling me that I wasn't loud enough.
...I later found out who (bass tbn) had just recorded many of them - under his direction...someone I sort-of consider to be a "pig", so...
...In the distant past, I played those arrangements on F tuba, but I eventually decided that the resonance was just too "rich".
He may have not thought much my bass trombone playing (all those years ago), but - well - I don't think using the brass to add a bunch of "ta-daaa's !!", "uh-ka-tuh-paaaaa's !!!", nor "what-the-hell-is-this-going-to-end-up-being...!?!? intro's" are particularly creative nor musicals way to use the brass, so I guess Dick and I are even.
(John Rutter is a true talent, as far as hymn settings, orchestration, and composition are concerned.)
...but I'll damn well play Dick's arrangements (again) to the best of my ability, and do my very best to sell them to the congregation.
