Also, from the description on the parish website, the previous director was singing some antiphonal chant and chant propers, possibly, and had a good-sized choir: https://seascc.org/worship/music-choir/
Seems like I've seen this church advertised at least a couple of times over recent years. Just checked out the site: 7 weekend Masses and no assistance listed in the staff directory for music. If the outgoing director was having to do all of these every weekend, when coupled with probably a copious amount of weddings and funerals and other responsibilities, this looks like a recipe for burnout.
I used to live in the area and have attended a few Masses and other services there (pretty sure I went to Stations of the Cross once).
It is HUGE. And a little weird. (By weird, I mean - for example - they have a life-sized replica of the Shroud of Turin in their narthex.)
It was also (at the time) served by more than one former Anglican married priest with relatively conservative/traditionalist liturgical preferences. (There are a lot of those in that Diocese, as the Episcopal Diocese of Fort Worth (formerly TEC, now ACNA) was a magnet for, and generator of, Nashotah House AngloCatholics, many of whom eventually swam the Tiber.
