September 17, 2022 – Interview: Riveting Riffs Magazine:

“These are heady days for actress and singer Sierra Rein, she has now returned to what she enjoys doing most in life, performing on stage and in front of a camera, after two years of much of the arts world being put on an involuntary pause due to COVID. She has two podcasts on the go, a short film in post-production, appears in two episodes of a series to be broadcast and streamed on FX on Hulu this fall and she has several exciting music gigs coming up. Believe or not that is just barely scratching the surface.” (Read the full Interview here)

“Sunday. Please be the last song. I can’t handle more tears. I know this performance. It’s Marquee Five. They have perfected this performance. This has to be the last song, they couldn’t possibly end the album any other way. OH, THESE HARMONIES! Kill me, now. Album highlight. (Marquee Five)”

Bite-Sized Broadway: A Mini-Musical Podcast consists of 50-minute episodes each featuring a 10-to-20-minute “mini-musical” presented as a fully produced radio play complete with top-of-the-line digital orchestrations and captivating sound effects. Each musical is followed by a discussion with its writers about their piece and their careers. In order to support these gifted writers, we have cast top Broadway and theatre industry talent to help get eyes and ears on these writers and help them launch a fruitful career in the theatre.
