Born and raised in Wisconsin, Rebecca Sjöwall has been lauded for her dramatic power as an actress ("electrifying," "striking," "a joy to watch") with a voice described as "luscious," "beautifully crisp," and "a powerhouse." Of her recent role debut with Nashville Opera as Mrs. P in Nyman's The Man Who Mistook His Wife for a Hat, ArtsNash declared, "Her climactic singing scream of 'Philistine!' at Dr. S is one of the most electrifying moments I've experienced in more than 40 years of attending live opera and theater performances." Naxos released a studio recording of the opera, recorded at Ocean Way Nashville, in September 2016.

Over five million gamers have heard Rebecca's voice as the singer of the "Rapture Anthem" on the popular video games BioShock and BioShock 2. The pop/rock band Sparks invited her to portray the sassy Hollywood Starlet for their album The Seduction of Ingmar Bergman, a role that she reprised for a sold-out live performance presented by the L.A. Film Fest at the Ford Amphitheatre in Hollywood. As a two-time Society of Singers scholarship recipient, she was honored to open for Smokey Robinson at their 16th Annual ELLA Awards.

Rebecca made her Nashville Opera role and company debut as the Williamson girl in David Lang's The Difficulty of Crossing a Field. In the fall of 2016, she returned to Nashville once again, this time to portray Older Alyce in Tom Cipullo's heart-wrenching opera Glory Denied. She made her Opera Idaho debut in that same role in the spring of 2016. In 2014, Rebecca made her role and company debut with Pacific Opera Project as the Governess in Britten's The Turn of the Screw, about which Stage and Cinema wrote, "Her dramatic expression and stunning voice exhibit great beauty and power." She reunited with POP the following year as Alice Ford in Verdi's Falstaff. She spent two seasons honing her craft as a studio artist with Arizona Opera, performing five mainstage roles including the High Priestess in Verdi's Aida, Kate Pinkerton in Puccini's Madama Butterfly, and Amore in Gluck's Orfeo ed Euridice.

Rebecca made her Carnegie Hall debut in a world premiere by Stephen Edwards and collaborates often with many composers. She participated in two world premiere operas by Kenneth Wells, first as Anna Roosevelt in The First Lady ("an outstanding performance," wrote the LA Weekly) and then as Professor Elyn Saks in The Center Cannot Hold. As a guest soloist and in recital, Rebecca has performed repertoire including Verdi's Messa da Requiem, Brahms' Ein deutsches Requiem, Dvorak's Te deum, Vaughan Williams' Dona nobis pacem, and Beethoven's Symphony No. 9, and is particularly fond of Swedish, English, and German song.

While working on her bachelor's degree in political science at Luther College, Rebecca took her first voice lesson. She was planning a future studying law but wanted to see the world first. So, she headed to Japan to work as an English teacher. While living in a tiny mountain town north of Kyoto City, a fellow teacher asked if she would give a concert to raise money for The Friendship Foundation. It was a life-changing experience through which she got a glimpse of the connective power of music. After returning to the U.S., she began studying music. Five years later, after working full-time at Harvard Business School and then Rolex, she began her vocal performance studies at UCLA, where she later earned her master's in music.

A two-time District Winner of the Metropolitan Opera National Council Auditions as well as Winner of the American Jenny Lind Competition, Rebecca currently lives in Los Angeles.
