Saxe and the City: IndieWorks’ Benefit Performance

Sierra performed as part of composer showcase Saxe and the City at The Duplex, NYC, September 20, 2019:

“Sierra Rein’s convincing performance of “I Leap” showed off her diverse range when she sang, “It’s all up to me, here on the ledge, I pledge to make that Le—ap.” As she shied away from diving off and then followed through with that intention later in the song, we could really feel the character grow.” – Chris Struck, Cabaret Scenes

Marquee Five Performances

“Back Porch Swing” at The Laurie Beechman Theater, New York City, March 1, 2019:

“Alto Sierra Rein’s vocal versatility is well-known in New York’s cabaret community, and kudos to Hemming for showcasing it in featured vocal lines that swooped thrillingly from deep in her chest register up into the stratosphere. A deeply grounded performer, her un-showoffy featured turns (I’ll Be Seeing You (Irving Kahal, Sammy Fain) and Stompin’ At The Savoy (Benny Goodman, Edgar Sampson, Chick Webb, Andy Razaf)) were riveting in their simplicity and vocal luster.” – Jennie Litt, Cabaret Hotspot.
