Phantom - Westchester Broadway Theater
"[Seidl] who captivates The Phantom with her Lily Pons pyrotechnical voice, sings coloratura high notes effortlessly…I kept thinking she would not be able to top her showstopper ‘Home’ in the first act, but I was wrong!"
"She charms the audience as she moves effortlessly across the stage. When she sings, her amazing vocal performance soars through the theater capturing and lifting the audience. On opening night we witnessed a future Broadway star on the Westchester stage."
"After the show, Maury Yeston told me, ‘This is absolutely among the top productions ever done of this musical."
"‘You are Music’ delivered by Ms. Seidl…ranks as one of the most moving musical numbers and performances I have heard in recent memory."
"Ms. Seidl will make you weep...If you want a Christine to take under your wing because you think she's fabulous, well, sir, Ms. Seidl's Christine is she."
"Ms. Seidl possesses the spectacular soprano to pull off the role of Christine and she lit up the stage."
Guys and Dolls National Tour
"Seidl has to occupy the show’s least dimensional role, that of a virginal do-gooder who finds herself smitten by Masterson on a trip to Cuba. And still, she makes the role her own, using moments of quiet intensity that work effectively to offset the scenes where the wild inner Sarah Brown finally breaks loose."
"Seidl's superb soprano is just lovely and she even displays a bit of sassy-ness."
"Seidl’s soaring, pitch perfect soprano was a joy to the ear, effortlessly gliding over the most challenging notes, filling the auditorium with clear sound, comparable only to the ringing of a flawless crystal bell."
"Powerful duets and a playful dance number shared between [Matthew Taylor and Kayleen Seidl] were highlights of the production, as was watching Seidl take her character from lady to “doll” and back again through a transformative vocal performance."
"Sarah, leader of the Save-A-Soul Mission, is a beautiful "mission doll" with a spunky personality. Seidl sings and acts with natural charm."
"Seidl is stubborn and self-assured in this role, and I enjoyed her performance. Her vocals in "Many a New Day" are strong and endearing."
"Seidl's Laurey is more than pretty and confused about men; she's really conceivable as a very young woman holding down a farm."
It Shoulda Been You
"As bride Rebecca, Kayleen Seidl also has a marvelous singing voice, which she uses well in a second-act song of self-validation, 'A Little Bit Less Than.'"
"Kayleen Seidl, in the female leading role of Magnolia, is another wonderful singer, with a soaring soprano voice that is pure, and sweet. This belle not only sings well, she's got the acting chops to match."
"She sparkles onstage and so does her voice."
