Yes, I'm in LA. I followed murphE's links from an earlier post and made my way to a Una Voce Los Angeles chapter. They listed when and where the Latin Masses are in the LA area. Does Salamunvich's parish have a Tridentine Mass?
Una Voce Orange County has or at least had a very active chapter. I think the indult crowd moved from St. Mary's by the Sea in Huntington Beach to the remaining indult at San Juan Capistrano or Our Lady Help of Christians.
Angelus Press and the FSSP website have new Traditional missals for sale. They both are supposed to be good (I haven't seen either). Fr. Lasance's missal and the St. Andrew's missal are commonly used older missals. AP, FSSP and probably TAN books and Catholic Treasures all sell missals.
No--Paul's parish (St Charles Borromeo) does NOT have a Tridentine Mass.
But when Paul's directing the music, there is NO trash, period. Paul's last 'outside' gig was as Director of the LA Master Chorale--he was also the choral director for Marymount before and after the merger w/Loyola.
