Taylor Swift Kicks Off L.A. Concerts, Performs Rare Song Live For First Time

The City of Angels is officially the City of Swifties -- Taylor Swift has kicked off her 6 sold-out shows in Los Angeles, and fans had a lot to go wild over on night number 1.

Taylor took the stage Thursday night at SoFi Stadium for her "Eras" tour ... rockin' the crowd of over 70,000 after a killer opening act by HAIM. She brought the sister group back out later in the night to perform "No Body, No Crime" together.

TS had a surprise for her L.A. fans ... dusting off "I Can See You" from "Speak Now (Taylor's Version") -- the first time she's ever performed it live. Safe to say, the crowd went ballistic.

Swifties also pointed out a fun fact -- Taylor sang "August" from her "Folklore" album in August for the first time ... pretty neat.

It was a star-studded event at SoFi ... Vanessa Bryant was there with her daughters, Natalia and Bianka. tWitch's wife Allison Holker was in the crowd, as was Ashley Tisdale, Nick and Vanessa Lachey, and "Outer Banks" star Madelyn Cline -- and that was just Thursday.

As we reported, the LAPD is working with Metro to help with the flood of fans heading to and from SoFi while Taylor's in town ... beefing up the amount of officers throughout the big Metro system.

The L.A. County Sheriff's Department said it's "providing a similar level of visibility as the 2022 Superbowl" ... in other words, LAPD ain't messing around when it comes to Taylor!!
