As Taylor swift readies to open TOMORROW NIGHT in Los Angeles - the last North American stop on her blockbuster ERAS tour, she and her management have not taken for granted all that goes into creating one of the biggest live spectacles of the year. The ability to pull off a show of enormous scale, night after night, that’s loaded with gorgeous set designs, dazzling costumes, cutting-edge lighting effects, and more takes a phenomenal team — and the superstar is expressing her gratitude where it counts.

We’re told that Taylor recently gave bonuses to each person working on her show. This includes everyone from dancers to sound technicians, catering to riggers, and more. Total tab: $55 million. The mega artist also reportedly gifted $100,000 bonuses EACH to around 50 of her production truck drivers as well, handing out the bonus checks before her Saturday show in Santa Clarita, CA.

Having kicked off The Eras Tour on March 17 in Glendale, Arizona, the singer-songwriter’s sold-out shows have garnered more than 70,000 fans each night. Taylor’s first L.A. show kicks off tomorrow, August 3rd at SoFi Stadium in Los Angeles with the first of 6 nightly performances running through next Wednesday, Aug. 9, which will officially wrap the U.S. leg of the tour. The Eras Tour then begins a Latin American series of shows in Mexico, Brazil and Argentina.

To date, Taylor's nationwide tour has raked in over $1 billion in sales ... and when the dust settles, she could end up having one of the highest-grossing tours of all time.
