[6] Sater and Sheik continued their stage work with Spring Awakening, a musical interpretation of German playwright Frank Wedekind's play of the same name.

Spring Awakening has had two national tours and international productions in over 49 countries, including Australia, Sweden, Japan, Israel, Serbia, Brazil, Korea, Argentina, Norway, Russia, and Great Britain (in London, at the Lyric Hammersmith and Novello Theatres).

[9] After receiving numerous requests to discuss the poetry of the Spring Awakening lyrics, Sater undertook writing a companion book on the subject.

[12] In 2010, Sater and Sheik began workshopping Alice by Heart with a group of students from Harvard-Westlake School in Los Angeles, including Molly Gordon, Ben Platt, Beanie Feldstein, Jack Quaid, Darren Criss, and Kathryn Gallagher.

[13] In 2011, Sater and Sheik received a commission from the Royal National Theatre: Connections to further their work on the musical, which is inspired by Lewis Carroll's Alice's Adventures in Wonderland and tells the story of Alice Spencer, a young girl seeking refuge with her quarantined and ailing friend Alfred Hallam, in her reimagining of Wonderland and also in the physical world of a battered Tube Station during the Blitz of World War II.

In the US, Alice by Heart was workshopped with Theatre Aspen in 2014, featuring Molly Gordon, Mike Faist, Noah Galvin, and Phillipa Soo.

[15] In 2015, MCC Theater produced a workshop featuring Molly Gordon, Ben Platt, Ashley Park, Anthony Ramos, and Mary Testa.

The production featured Molly Gordon, Colton Ryan, Wesley Taylor, Noah Galvin, Grace McLean, Andrew Kober, and Heath Saunders.

On February 4, 2020, Razorbill published Sater's novel to excellent reviews, terming it, "an extraordinary blend of historical fiction and Lewis Carroll’s timeless classic."

The project was subsequently workshopped with New York Stage and Film at Vassar College in July 2008, starring Idina Menzel, Lea Michele, Jeffrey Carlson, and Michael Arden, under the direction of Daniel Kramer.

The piece, also called "The Nightingale", was presented in a Page to Stage production at La Jolla Playhouse in summer 2012 (directed by Moises Kaufman and produced by Dodgers Theatricals).

[22] Sater and Sheik are currently developing a stage musical adaption of the 1995 Golden Globe-winning film Ma Vie en Rose, which tells the story of a seven-year old trans girl and the challenges she and her family face after she comes out in their provincial Belgian town.

Sater has worked with System of a Down's Serj Tankian on a musical version of Aeschylus's tragedy, Prometheus Bound, directed by Diane Paulus, which opened at the American Repertory Theater on March 4, 2011, to good reviews.

Produced by Ryan Seacrest Productions, with a pilot directed by Marc Webb, the show, co-written with Lauren Gussis, will tell an original non-binary love story.

[33] In the television series 90210, the first few episodes contain the school and some of the characters as they prepare, and eventually perform in Spring Awakening, though in reality the amateur production rights were not available at the time.

Further recorded songs include: "Trash" (Play), "Ragdoll" (Lucy Woodward), "Some Lovers" (Rumer), "Come In Ogni Ora" (Karima, Burt Bacharach), "Just Walk Away" (Karima, Burt Bacharach), "Something That Was Beautiful" (Mario Biondi), "The Hunger" (Shirley Manson, Serj Tankian), "Another Heaven" (Yisabel Jo), "Another Silent Christmas Song" (Jessica Sanchez and Christian Bautista).
